by the thiolene click reaction. It proceeds upon visible light catalysis with 9-phenylacridine providing various difluorinated sulfides as radical precursors. Single electron reduction of the C–S bond with the formation of fluoroalkyl radicals is enabled by the electron-poor azine ring. The intermediate difluorinated sulfides were involved in a series of photoredox reactions with silyl enol ethers

A novel reactivity pattern of gem-difluorinated organozincs in copper(I) catalyzed reaction with β-nitrostyrenes is described. The reaction proceeds not as conjugate addition, but as nitro group substitution furnishing alkenes as single E-isomers in moderate yields.
