A visible light accelerated C-H functionalization reaction in Pd-catalyzed arylation of vinyl arenes with diaryliodonium salts is reported in the absence of addnl. photosensitizer. The kinetic isotope effect (kH/kD) was changed from 3.6 (under darkness) to 1.1 when irradiated by visible light, which indicated that the C-H functionalization step was the rate determining step under darkness and significantly accelerated by the irradiation of visible light. Finally the synthesis of ortho tetra-substituted vinylarene atropisomers with high enantiospecificity was realized via this protocol. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Quality Control of Bis(2,4,6-trimethylphenyl)iodonium triflate).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Quality Control of Bis(2,4,6-trimethylphenyl)iodonium triflate
