On December 31, 1982, Bolton, Roger; Moore, Clive; Sandall, John P. B. published an article.Computed Properties of 364-12-5 The title of the article was Nucleophilic displacement in polyhaloaromatic compounds. Part 11. Kinetics of protiodeiodination of iodoarenes in dimethyl sulfoxide-methanol. And the article contained the following:

The kinetics were determined of the MeO–induced protiodeiodination of 15 polychloroiodobenzenes and 6 of their Br- or CF3-substituted analogs in 9:1 (volume) DMSO-MeOH at 323.2 K. The true reagent is the DMSO anion. The reaction rates in some cases approached the diffusion-controlled process. Cl and CF3 substituents promote the reaction in the order ortho > meta > para and ortho > para > meta, resp. Protiodeiodinaton is promoted by o-NO2 groups, but the p-NO2 group encourages methoxydeiodination. Unlike polychloroiodobenzenes, polychlorobenzenes underwent methoxydechlorination. A mechanism involving nucleophilic attack by a carbanion was proposed. The experimental process involved the reaction of 5-Bromo-2-iodobenzotrifluoride(cas: 364-12-5).Computed Properties of 364-12-5

The Article related to aryl iodide protiodeiodination kinetics, substituent effect protiodeiodination iodoarene, chlorobenzene methoxydechlorination kinetics, iodochlorobenzene substitution methanol kinetics and other aspects.Computed Properties of 364-12-5

On November 21, 2009, Plietzsch, Oliver; Schilling, Christine Inge; Tolev, Mariyan; Nieger, Martin; Richert, Clemens; Muller, Thierry; Brase, Stefan published an article.Application In Synthesis of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane The title of the article was Four-fold click reactions: Generation of tetrahedral methane- and adamantane-based building blocks for higher-order molecular assemblies. And the article contained the following:

A modular concept for the generation of achiral and chiral non-racemic tetrahedral tectons from common precursors was developed. The tectons presented here are based on tetraphenylmethane or 1,3,5,7-tetraphenyladamantane core structures. They are obtained through high-yielding four-fold click reactions, using either the tetraazido or the tetraalkyne precursors. In most cases, the tetratriazoles are obtained as pure products after simple washing with water and methanol. The side chains of the tectons prepared include a self-complementary DNA dimer, obtained from a 3′-azidonucleoside and a phosphoramidite. The concept allows for a variation of the “sticky ends”, leading to tecton or ligand libraries. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Application In Synthesis of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane

Boldog, Ishtvan; Domasevitch, Konstantin V.; Baburin, Igor A.; Ott, Holger; Gil-Hernandez, Beatriz; Sanchiz, Joaquin; Janiak, Christoph published an article in 2013, the title of the article was A rare alb-4,8-Cmce metal-coordination network based on tetrazolate and phosphonate functionalized 1,3,5,7-tetraphenyladamantane.Recommanded Product: 144970-30-9 And the article contains the following content:

Sym. tetrahedral ligands are prominent, but somewhat under-studied building blocks for the generation of coordination polymeric networks. Coordination networks [Mn5Cl2(L1)2(H2O)4(DMF)4]·3H2O·7DMF, 1 and the [La2(H5L2)2(H2O)6], 2 were synthesized under mild solvothermal methods in DMF from the adamantane-based tetrahedral ligands, 1,3,5,7-tetrakis(4-phenyltetrazol-5-yl)adamantane (H4L1), reported for the first time, and 1,3,5,7-tetrakis(4-phenylphosphonic acid)adamantane (H8L2), resp. Compounds 1 and 2 are based on completely different pentanuclear and binuclear secondary metal building units, resp., and have different symmetries, but demonstrate an interesting coincidence of underlying topologies, which could be interpreted as a directing or imprinting’ effect of the symmetry of the rigid tetrahedral ligands. Both structures represent examples of a rarely observed (4,8)-coordinated net. The χMT product for 1 at room temperature is slightly lower than the expected for five Mn(II) ions with S = 5/2 and g ≈ 1.98 and on lowering the temperature χMT approaches the expected value for a single Mn(II) as a result of the antiferromagnetic coupling through the tetrazolate bridges. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Recommanded Product: 144970-30-9

On July 15, 2022, Nguyen, Viet D.; Trevino, Ramon; Greco, Samuel G.; Arman, Hadi D.; Larionov, Oleg V. published an article.HPLC of Formula: 1287221-36-6 The title of the article was Tricomponent Decarboxysulfonylative Cross-coupling Facilitates Direct Construction of Aryl Sulfones and Reveals a Mechanistic Dualism in the Acridine/Copper Photocatalytic System. And the article contained the following:

A dual catalytic process that enabled the previously inaccessible, broad-scope, direct conversion of carboxylic acids to aromatic sulfones-centrally important carbonyl group bioisosteric replacements and synthetic intermediates-by a tricomponent decarboxysulfonylative cross-coupling with aryl halides was reported. Detailed mechanistic and computational studies revealed the roles of the copper catalysts, bases and halide anions in channeling the acridine/copper system via a distinct dual catalytic manifold. In contrast to the halide-free decarboxylative conjugate addition that involved cooperative dual catalysis via low-valent copper species, the halide counteranions divert the decarboxysulfonylative cross-coupling with aryl halides through a two-phase, orthogonal relay catalytic manifold, comprising a kinetically coupled (via antithetical inhibitory and activating roles of the base in the two catalytic cycles), mechanistically discrete sequence of a photoinduced, acridine-catalyzed decarboxylative process and a thermal copper-catalyzed arylative coupling. The study underscores the importance of non-innocent roles of counteranions and key redox steps at the interface of catalytic cycles for enabling previously inaccessible dual catalytic transformations. The experimental process involved the reaction of 4-Iodophenylboronic acid MIDA ester(cas: 1287221-36-6).HPLC of Formula: 1287221-36-6

And the article contained the following:

Three tripodal Ru(II)-polypyridyl complexes were synthesized as models to study long-range electron transfer in TiO2 semiconductor nanoparticle thin films, in particular to study the effect of the conjugation of the bridge containing the Ru complex and for distance-dependence studies. The tripodal sensitizers, which are 1,3,5,7-tetraphenyladamantane derivatives having three COOMe anchoring groups and one rigid-rod bridge substituted with a Ru(II) complex, are the longest prepared to date (Ru-to-footprint distance ∼24 Å). Two have a rigid-rod bridge made of two p-ethynylphenylene units (Ph-E)2 capped with a 4-(2,2′-bipyridyl) (bpy) ligand or a 5-(1,10-phenanthrolinyl) (phen) ligand for the Ru complex. The third tripod, which contains a bpy ligand for the Ru complex, has one bicyclo[2.2.2]octylene (Bco) unit in place of a p-phenylene (Ph) unit and is the first example of a tripodal sensitizer with a nonconjugated bridge. Solution absorption and fluorescence data of the three complexes are reported. Photophys. studies of the non-conjugated Bco-bridged complex on TiO2 are not reported. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Name: 1,3,5,7-Tetrakis(4-iodophenyl)adamantane
