An unprecedented triple catalytic, general ring-opening cyanation reaction of cyclopropyl ketones I (R = Ph, 3,4-dichlorophenyl, prop-1-en-1-yl, etc.; R1 = H, CO2C(CH3)3; R2 = Ph, 4-fluorophenyl, 2-naphthyl, etc.) for the construction of γ-cyanoketones R2C(O)CH2CH(R1)CH(R)CN is described. The key is to merge photoredox catalysis with Lewis acid catalysis and copper catalysis to enable the selective cleavage of the carbon-carbon bonds and the selective coupling of the generated radical and cyanide anion. In the experimental materials used by the author, we found Trimethylsulfoxonium iodide(cas: 1774-47-6Recommanded Product: Trimethylsulfoxonium iodide)
Trimethylsulfoxonium iodide(cas: 1774-47-6) is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides.Recommanded Product: Trimethylsulfoxonium iodide
