Visible light-mediated cascade remote oxyfluoroalkylation of alkenes under mild conditions is developed for the first time. The key point of this transformation is the incorporation of alkene fluoroalkylation-initiated remote benzyl C-H bond activation via a 1,5-H shift in a highly controlled site-selective manner and Kornblum reaction with DMSO as the oxidant. With this method, a broad array of fluoroalkyl groups were introduced into a double bond to produce 1,6-fluoroalkylated ketones at room temperature In the part of experimental materials, we found many familiar compounds, such as fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Computed Properties of C33H24IrN3)

fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene.

A light-driven atom-transfer radical substitution (ATRS) and carboesterification reaction of alkenes with alkyl halides has been developed using PTH (N-phenylphenothiazine) as the organo-photoredox catalyst.
