The visible-light-induced C—C bond cleavage of dihydroquinazolinone to generate alkyl radicals for defluorinated alkylation reactions with α-trifluoromethyl alkene is reported. The method is featured as transition-metal-free, mild conditions, base- or additive-free, and has a wide range of substrate applicability, which provides a convenient and efficient new method for the synthesis of various alkyl-substituted gem-difluoroalkene.

Key words: visible-light catalysis, dihydroquinazolinone, C—C bond cleavage, gem-difluoroalkene, α-trifluoromethyl alkene
