摘要：
A radical defluorinative alkylation method of 1-trifluoromethyl alkenes and 1,3-butadienes with 4-alkyl-1,4-dihydropyridines under visible light irradiation is presented. Various alkylated 1,1-difluoroalkenes and 1,1-difluorodienes were obtained in moderate to high yields through a sequential C-C and C-F bond cleavage process.
