Visible light-induced radical 5/6-endo-trig difluoroalkylation/cyclization of N-allyl and homoallyl aldehyde hydrazones with various fluoroalkyl bromides has been achieved. The reaction was carried out alkyl difluoroacetates difluoroacetamide as difluoroalkylation reagents Eosin Y an organic photocatalyst. Various difluoroalkylated dihydropyrazoles tetrahydropyridazines were obtained under metal-free mild conditions.
