资源简介：
Visible-light-induced
metal-free trifluoromethylation of activated,
carbocyclic, and unactivated vinylcyclopropanes via a ring-opening
reaction using the Langlois reagent (CF3SO2Na)
is reported to synthesize allylic trifluoromethylated derivatives.
Allylic trifluoromethylation was achieved by a photo-oxidative single
electron transfer (SET) process at an ambient temperature and under
metal-free conditions and visible-light irradiation using pyrylium
salt as a photoredox catalyst. The reported methodology has an operational
simplicity, broad substrate scope, high functional group tolerance,
and scalability.
