《Ligand-Controlled Direct γ-C-H Arylation of Aldehydes》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Li, Bijin; Lawrence, Brianna; Li, Guigen; Ge, Haibo. Product Details of 624-31-7 The article mentions the following:

The first example of PdII-catalyzed γ-C(sp3)-H functionalization of aliphatic and benzoheteroaryl aldehydes was developed using a transient ligand and an external ligand, concurrently. A wide array of γ-arylated aldehydes were readily accessed without preinstalling internal directing groups. The catalytic mechanism was studied by performing deuterium-labeling experiments, which indicated that the γ-C(sp3)-H bond cleavage is the rate-limiting step during the reaction process. This reaction could be performed on a gram scale, and also demonstrated its potential application in the synthesis of new mechanofluorochromic materials with blue-shifted mechanochromic properties. In the experiment, the researchers used 1-Iodo-4-methylbenzene(cas: 624-31-7Product Details of 624-31-7)

Liu, Kun; Studer, Armido published their research in Journal of the American Chemical Society in 2021. The article was titled 《Direct α-Acylation of Alkenes via N-Heterocyclic Carbene, Sulfinate, and Photoredox Cooperative Triple Catalysis》.Name: Trimethylsulfoxonium iodide The article contains the following contents:

N-Heterocyclic carbene (NHC) catalysis has emerged as a versatile tool in modern synthetic chem. Further increasing the complexity, several processes have been introduced that proceed via dual catalysis, where the NHC organocatalyst operates in concert with a second catalytic moiety, significantly enlarging the reaction scope. In biol. transformations, multiple catalysis is generally used to access complex natural products. Guided by that strategy, triple catalysis has been studied recently, where three different catalytic modes are merged in a single process. In this Communication, direct α-C-H acylation of various alkenes with aroyl fluorides using NHC, sulfinate, and photoredox cooperative triple catalysis is reported. The method allows the preparation of α-substituted vinyl ketones in moderate to high yields with excellent functional group tolerance. Mechanistic studies reveal that these cascades proceed through a sequential radical addition/coupling/elimination process. In contrast to known triple catalysis processes that operate via two sets of interwoven catalysis cycles, in the introduced process, all three cycles are interwoven. The experimental process involved the reaction of Trimethylsulfoxonium iodide(cas: 1774-47-6Name: Trimethylsulfoxonium iodide)

Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry.

Pipitone, Candida; Giannici, Francesco; Martorana, Antonino; Garcia-Espejo, Gonzalo; Carlotto, Silvia; Casarin, Maurizio; Guagliardi, Antonietta; Masciocchi, Norberto published their research in Journal of Physical Chemistry C in 2021. The article was titled 《Heterovalent BiIII/PbII Ionic Substitution in One-Dimensional Trimethylsulfoxonium Halide Pseudo-Perovskites (X = I, Br)》.Application of 1774-47-6 The article contains the following contents:

The authors report on the synthesis and characterization of novel lead and Bi hybrid (organic-inorganic) iodide and bromide pseudo-perovskites (ABX3) containing the trimethylsulfoxonium cation Me3SO+ (TMSO) in the A site, Pb/Bi in the B site, and Br or I as X anions. All of these compounds are isomorphic and crystallize in the orthorhombic Pnma space group. Pb-based pseudo-perovskites consist of 1-dimensional (1D) chains of face-sharing [PbX6] octahedra, while in the Bi-based ones, the chains of [BiX6] are interrupted, with one vacancy every 3rd site, leading to a zero-dimensional (0-D) local structure based on separated [Bi2I9]3- dimers. Five solid solutions for the iodide with different Pb2+/Bi3+ ratios between (TMSO)PbI3 and (TMSO)3Bi2I9, and two for the bromide counterparts, were synthesized. Due to the charge compensation mechanism, these systems are best described by the (TMSO)3Pb3xBi2(1-x)I9 (x = 0.98, 0.92, 0.89, 0.56, and 0.33) and (TMSO)3Pb3xBi2(1-x)Br9 (x = 0.83 and 0.37) formulas. X-ray powder diffraction (XRPD) measurements were employed to determine the crystal structure of all studied species and further used to test the metal cation miscibility within monophasic samples not showing cation segregation. These systems can be described through an ionic defectivity on the pseudo-perovskite B site, where the Pb2+/Bi3+ replacement is compensated by one Pb2+ vacancy for every Bi3+ pair. This leads to a wide range of possible different (numerical and geometrical) chain configurations, leading to the unique features observed in XRPD patterns. The optical band gap of the iodide samples falls in the 2.11-2.74 eV range and decreases upon increasing the Bi3+ content. Even a very low loading of Bi3+ (1%) is sufficient to reduce the band gap substantially from 2.74 to 2.25 eV. Periodic d. functional theory (DFT) calculations were used to simulate the at. and electronic structures of the authors’ samples, with predicted band gap trends in good agreement with the exptl. ones. This work highlights the structural flexibility of such systems and accurately interprets the ionic defectivity of the different pseudo-perovskite structures.

Chaisan, Nattawadee; Ruengsangtongkul, Sureeporn; Tummatorn, Jumreang; Ruchirawat, Somsak; Chainok, Kittipong; Thongsornkleeb, Charnsak published an article in 2021. The article was titled 《Dibrominative Spirocyclization of 2-Butynolyl Anilides: Synthesis of gem-Dibromospirocyclic Benzo[d][1,3]oxazines and Their Application in the Synthesis of 4H-Furo[3,2-b]indoles》, and you may find the article in Journal of Organic Chemistry.Quality Control of 4-Chloro-2-iodoaniline The information in the text is summarized as follows:

The combination of catalytic aqueous hydrochloric acid (HCl) and N-bromosuccinimide (NBS) generated electrophilic bromine monochloride (BrCl), which readily induced spiroannulation of 2-alkynolyl anilides I (n = 1,2, X = Cl, Br; n = 3, X = Br; R1 = H, 6-Me, 7-Cl, 6-CN, etc.; R2 = Ph, tert-Bu, cyclohexyl, etc.; R3 = H, Ph) to form gem-dibromospirocyclic benzo[d][1,3]oxazines II in up to 92% yield. The reaction occurred under mild and metal-free conditions using EtOAc as a green solvent. The resulted spirocyclic products contained benzo[d][1,3]oxazine II, which was useful both as a pharmacophore and synthetic precursor. In addition, the current protocol allowed to effortlessly introduce the sp3-gem-dibromide carbon adjacent to the sterically demanding spiroketal center. These spiroheterocycles (n = 1) were shown to be synthetically versatile and conveniently maneuvered. Base-promoted debrominative aromatization of these spirocycles II (n = 1; X = Br) unmasked rare and synthetically useful 2-aryl-3-bromofurans III in mostly excellent yields. These 3-bromofurans III were well-suited substrates for intramol. Ullmann C-N bond coupling to construct difficult-to-prepare 4H-furo[3,2-b]indoles IV. Addnl., the current protocol was flexible and adaptable to prepare the gem-dichloride variants.

The article was titled 《Formation of 1-D/3-D Fused Perovskite for Efficient and Moisture Stable Solar Cells》, and you may find the article in ACS Applied Energy Materials.Category: iodides-buliding-blocks The information in the text is summarized as follows:

Various organic cations (e.g., methylammonium (MA+), butylammonium (BA+), formamidinium (FA+), etc.) have been studied and used in organometallic halide perovskite solar cells (PSCs). Most of the currently used organic cations are protic in nature, which can induce acid-base reactions and, thus, lead to degradation of the perovskites. So far, the role of aprotic cations in PSCs has not been studied much. In the present study, two aprotic cations, namely, trimethylsulfonium (TMS+) and trimethylsulfoxonium (TMSO+), are introduced into lead-based PSCs to form one-dimensional/three-dimensional (TMSPbI3)x(MAPbI3)100-x and (TMSOPbI3)x(MAPbI3)100-x perovskite structures, resp. This is shown to provide enhanced performance and moisture resistance, thus, increasing the stability and lifespan of the PSCs. The power conversion efficiencies of the (TMSPbI3)x(MAPbI3)100-x and (TMSOPbI3)x(MAPbI3)100-x devices are found to be 19.34 and 19.94%, resp., compared to 17.11% for the pristine MAPbI3 PSC, along with enhanced open-circuit voltages (VOC) of 1.14 and 1.12 V, resp., compared to 1.07 V for the pristine MAPbI3 PSC. Furthermore, the effects of TMS+ and TMSO+ upon the perovskite structure, absorption, recombination, and film morphol. are discussed in detail. The results of this study will be helpful in the exploration of sulfur-based cations for the development of more stable PSCs.
