Usage

Description

4-Iodobenzotrifluoride, also known as α,α,α-trifluoro-4-iodotoluene, is an organic compound characterized by its electron-deficient aromatic ring and a trifluoromethyl group. It is a clear red to pink liquid with the odor of halogenated benzene and is insoluble in water but miscible with various organic solvents such as benzene, toluene, ethanol, ether, and halogenated hydrocarbons. 4-Iodobenzotrifluoride is known for its special activity due to the presence of a fluorine atom in its molecular structure.

Uses

Used in Chemical Synthesis:
4-Iodobenzotrifluoride is used as a substrate with an electron-deficient aromatic ring for the Mizoroki-Heck reaction with acrylic acid, resulting in the formation of 4-trifluoromethylcinnamic acid. This application takes advantage of the compound's reactivity in cross-coupling reactions, which are widely used in the synthesis of various organic compounds.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, 4-Iodobenzotrifluoride is utilized as an intermediate in the synthesis of various pharmaceutical compounds. Its unique structure and reactivity make it a valuable building block for the development of new drugs.
Used in Pesticide Industry:
4-Iodobenzotrifluoride is an important intermediate in the production of pesticides, particularly the insecticide fipronil. 4-Iodobenzotrifluoride's special activity, attributed to the fluorine atom in its molecular structure, makes it a key component in the synthesis of this widely used insect control agent.
Used in Herbicide Synthesis:

A convenient synthetic approach to a novel class of aryldifluoromethyl pyrimidine derivatives containing strobilurin motif as insecticidal agents

A series of aryldifluoromethyl pyrimidine compounds containing strobilurin were synthesized through bioelectronic isometric design with azoxystrobin as the lead compound and a convenient approach to aryldifluoromethylpyrimidine intermediates was developed, which features mild reaction conditions and simple operation. The title compounds and aryldifluoromethylpyrimidine intermediates were characterized by NMR and HRMS. Both 7c and 7l of the preliminary screening tests showed 100% inhibition against Mythimna separata at 100 mg/L. At 20 mg/L, the lethal rate of 7l against Mythimna separata can be up to 80%.

Cross-Coupling through Ag(I)/Ag(III) Redox Manifold

In ample variety of transformations, the presence of silver as an additive or co-catalyst is believed to be innocuous for the efficiency of the operating metal catalyst. Even though Ag additives are required often as coupling partners, oxidants or halide scavengers, its role as a catalytically competent species is widely neglected in cross-coupling reactions. Most likely, this is due to the erroneously assumed incapacity of Ag to undergo 2e? redox steps. Definite proof is herein provided for the required elementary steps to accomplish the oxidative trifluoromethylation of arenes through AgI/AgIII redox catalysis (i. e. CEL coupling), namely: i) easy AgI/AgIII 2e? oxidation mediated by air; ii) bpy/phen ligation to AgIII; iii) boron-to-AgIII aryl transfer; and iv) ulterior reductive elimination of benzotrifluorides from an [aryl-AgIII-CF3] fragment. More precisely, an ultimate entry and full characterization of organosilver(III) compounds [K]+[AgIII(CF3)4]? (K-1), [(bpy)AgIII(CF3)3] (2) and [(phen)AgIII(CF3)3] (3), is described. The utility of 3 in cross-coupling has been showcased unambiguously, and a large variety of arylboron compounds was trifluoromethylated via [AgIII(aryl)(CF3)3]? intermediates. This work breaks with old stereotypes and misconceptions regarding the inability of Ag to undergo cross-coupling by itself.

Generation of Organozinc Reagents from Arylsulfonium Salts Using a Nickel Catalyst and Zinc Dust

Readily available aryldimethylsulfonium triflates react with zinc powder under nickel catalysis via the selective cleavage of the sp2-hybridized carbon-sulfur bond to produce salt-free arylzinc triflates under mild conditions. This zincation displays superb chemoselectivity and thus represents a protocol that is complementary or orthogonal to existing methods. The generated arylzinc reagents show both high reactivity and chemoselectivity in palladium-catalyzed and copper-mediated cross-coupling reactions.
