Rhodium-Catalyzed Direct C–H Bond Cyanation of Arenes with Isocyanide
摘要:
An efficient rhodium-catalyzed regioselective C-H bond cyanation of arenes was developed using tert-butyl isocyanide as the cyanide source. A wide range of (hetero)aryl and cycloalkenyl nitriles could be afforded with high regioselectivity and good functional group tolerance.
Synthesis of <i>gem</i>-difluoroalkenes <i>via</i> nickel-catalyzed allylic defluorinative reductive cross-coupling of trifluoromethyl alkenes with epoxides
nickel-catalyzed defluorinative reductive cross-coupling of trifluoromethyl alkenes with epoxides has been developed. Various substituted trifluoromethyl alkenes and epoxides were found to be suitable reaction substrates. This reaction enabled C(sp3)-C(sp3) bondconstruction through allylic defluorinative cross-coupling of trifluoromethyl alkenes under mild reaction conditions. This methodology was highly
