On November 16, 2018, Ormerod, Dominic; Dorbec, Matthieu; Merkul, Eugen; Kaval, Nadya; Lefevre, Nicolas; Hostyn, Steven; Eykens, Lies; Lievens, Jo; Sergeyev, Sergey; Maes, Bert U. W. published an article.Recommanded Product: 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1) The title of the article was Synthesis of Pd Complexes Containing Tailed NHC Ligands and Their Use in a Semicontinuous Membrane-Assisted Suzuki Cross-Coupling Process. And the article contained the following:

Homogeneous catalysis has proved to be a reliable method for preparing numerous mol. entities, but catalysts can be expensive and difficult to remove. Because of this, industry targets catalysts that are easily separated and recovered and feature increased turnover numbers The ongoing shift from multipurpose batch reactors toward continuous manufacturing in fine chems. synthesis results in a new set of catalyst requirements. This paper reports the design and use of Pd complexes suitable for a semicontinuous Suzuki cross-coupling reaction based on a membrane-assisted reactor. These Pd complexes contain tailed N-heterocyclic carbene (NHC) ligands, allowing internal catalyst recovery by organic solvent nanofiltration with top-layer-modified ceramic membranes. These membranes give selective nanofiltration of the catalyst based on a combination of size exclusion and affinity separation (solvent-solute-membrane interactions). The semicontinuous system developed led to significantly improved turnover numbers, simplified product isolation, and consequently reduced mass intensity by simply adding more of the reactants and reagents to the reaction vessel. The experimental process involved the reaction of 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1)(cas: 934008-48-7).Recommanded Product: 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1)

On July 26, 2021, Dorian, Andreas; Landgreen, Emily J.; Petras, Hayley R.; Shepherd, James J.; Williams, Florence J. published an article.Recommanded Product: 364-12-5 The title of the article was Iron-Catalyzed Halogen Exchange of Trifluoromethyl Arenes. And the article contained the following:

The facile production of ArCF2X and ArCX3 from ArCF3 using catalytic iron(III)halides is reported, which constitutes the first iron-catalyzed halogen exchange for non-aromatic C-F bonds. Theor. calculations suggest direct activation of C-F bonds by iron coordination. ArCX3 and ArCF2X products of the reaction are synthetically valuable due to their diversification potential. In particular, chloro- and bromodifluoromethyl arenes (ArCF2Cl, ArCF2Br resp.) provide access to a myriad of difluoromethyl arene derivatives (ArCF2R). To optimize for mono-halogen exchange, a statistical method called Design of Experiments was used. Optimized parameters were successfully applied to electron rich and electron deficient aromatic substrates, and to the late stage diversification of flufenoxuron, a com. insecticide. These methods are highly practical, being run at convenient temperatures and using inexpensive common reagents. The experimental process involved the reaction of 5-Bromo-2-iodobenzotrifluoride(cas: 364-12-5).Recommanded Product: 364-12-5

On December 23, 2015, Myahkostupov, Mykhaylo; Castellano, Felix N. published an article.COA of Formula: C34H28I4 The title of the article was Tetrahedral rigid core antenna chromophores bearing bay-substituted perylenediimides. And the article contained the following:

Two new representative methane- and adamantane-centered ‘antenna’ tetramers bearing bay-substituted 蟺-conjugated phenylethynyl-perylenediimides (PDICCPh) as chromophoric subunits, tetrakis-[1-(4-ethynylphenyl)-N,N’-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-methane (1) and tetrakis-1,3,5,7-[1-(4-ethynylphenyl)-N,N’-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-adamantane (2), were synthesized and their structural aspects were thoroughly studied by NMR spectroscopy. These PDI tetramers (1 and 2) represent the first successful example of incorporating the bay-substituted phenylethynyl-perylenediimides into the large rigid core tetrahedral frameworks. In these PDI tetramers, dynamic NMR experiments revealed the existence of perylene-centered conformational dynamic equilibrium (螖G鈮?15-17 kcal/mol), the primary cause of the observed spectral broadening in conventional 1H NMR spectra (295 K). In addition, PDI tetramers 1 and 2 were found to possess exceptional (photo)chem. stability, and their corresponding photophys. properties (蔚max鈭?80,000; 蟿FL=6.9 ns; 桅FL鈭?0%) make them viable candidates for various photonic applications and are in good agreement with other related multichromophoric PDI-based systems.

A.; Grosu, I.; Parvulescu, Vasile I.; Garcia, Hermenegildo published an article in 2016, the title of the article was An adamantane-based COF: stability, adsorption capability, and behavior as a catalyst and support for Pd and Au for the hydrogenation of nitrostyrene.Formula: C34H28I4 And the article contains the following content:

A bimodal (micro/mesoporous) COF was synthesized by coupling tetrakis-1,3,5,7-(4′-iodophenyl)adamantane with 4,4′-diethynylbiphenyl following a Sonogashira protocol. The COF preparation strategy led, however, to the incomplete recovery of the palladium catalyst and ICP-OES anal. indicated that around 0.1% palladium remained inside the pores. Noteworthily, the remnant palladium catalyst is still accessible and can be used in addnl. catalytic reactions like the hydrogenation of nitrostyrene. Further deposition of 0.5% active metals (like palladium or gold) enhanced the catalytic activity and tuned the catalyst selectivity with respect to analogous metal catalysts prepared using active carbon as a support. The resulting COF-supported metal NPs are stable and recyclable catalysts. Under normal conditions, this COF is also able to adsorb large amounts of weak electrophilic gases like carbon dioxide. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Formula: C34H28I4

Kaneko, Yuzuru; Hayashi, Mimi; Agata, Hideharu; Ichinohe, Tatsuya; Kaneko, Yuzuru published an article in 2001, the title of the article was Propofol does not change the platelet retention rate.HPLC of Formula: 364-12-5 And the article contains the following content:

An acceleration of platelet aggregations during and after surgery increases the risks of perioperative myocardial or cerebral infarction. It has been reported that isoflurane and sevoflurane depress platelet aggregation, but there are no convincing reports about the effects of propofol. We therefore investigated the effect of propofol on platelet aggregation by determining the platelet retention rate (PRR). Twenty-six consenting oral surgical patients classified in ASA phys. status I were randomly assigned to one of two groups (GOS group: n=13; GOP group: n=13). The patients in the GOS group were induced with thiopental sodium, nasotracheally intubated with vecuronium bromide, and maintained with 60% nitrous oxide and 1.5% sevoflurane in oxygen. The patients in the GOP group were induced with propofol, nasotracheally incubated with vecuronium bromide, and maintained with 60% nitrous oxide and 10 mg/kg/h propofol in oxygen. The PRR was determined by the collagen bead column method. Venous blood was collected three times in each group for the determination of PRR. The first PRR was measured before the induction of anesthesia, the second PRR, after the induction of anesthesia, and the third PRR, 5 min after submucosal injection of 5 mL of 1% lidocaine solution containing epinephrine (1:100,000). Data were analyzed using one-way ANOVA for repeated measurements followed by Student-Newman-Keuls test for intragroup comparisons and Student’s t-test for unpaired samples for intergroup comparisons p values less than 0.05 indicated statistical significance. The PRR in the GOS group decreased after induction (36.4卤12.5%) and increased after local anesthesia (52.3卤17.0%) when compared with that before induction (45.2卤14.2%). The PRR in GOP group did not decrease after induction (43.0卤13.0%), but it also increased after local anesthesia (56.0卤12.9%) when compared with that before induction (42.1卤13.1%). These data were all within normal ranges. The PRR changes after induction were -8.7卤9.1% in GOS group and 0.8卤6.2% in GOP group, resp. (p<0.05 between two groups). In contrast, the PRR increased in both groups after local anesthesia (GOS group = 15.8卤9.6%; GOP group = 13.8卤12.8%). In conclusion, propofol has no or minimal effect on platelet aggregation. The inhibitory effects of sevoflurane and propofol on epinephrine-induced platelet aggregation may be similar. The experimental process involved the reaction of 5-Bromo-2-iodobenzotrifluoride(cas: 364-12-5).HPLC of Formula: 364-12-5

On December 13, 2021, Okayasu, Misaki; Sunakawa, Toshiki; Ikeda, Mitsuru; Namikawa, Takaya; Hagura, Riho; Kikkawa, Shoko; Hikawa, Hidemasa; Azumaya, Isao published an article.Safety of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane The title of the article was Size and Shape Manipulation of Channel Structures Assembled Via Saddle stacking of Tetrapodal Adamantanes Containing Aryl Butadiynyl Moieties. And the article contained the following:

Three tetrapodal adamantane derivatives containing aryl butadiynyl moieties were synthesized under conditions similar to those of the Hay coupling reaction, and their crystal structures were analyzed. The substituted tetrapodal adamantanes were found to pile atop each other via saddle stacking to form 1D columnar structures, and the assembly of these 1D structures gave rise to channels in the crystal. Column assembly was achieved through CH/蟺 and 蟺-蟺 interactions between the terminal aromatic rings of the adamantanes belonging to adjacent columns. The channels thus formed had different shapes and sizes depending on the terminal aryl substituents, and were occupied by a suitable number of solvent mols. Compared to the adamantanes with Ph butadiynyl moieties as the terminal substituents, those with naphthyl butadiynyl moieties formed wider or thicker channels owing to their greater expanse perpendicular to the direction of saddle-stacking. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Safety of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane
