摘　　要：The sulfinatodehalogenation reaction of α,α-difluorobenzyl handes, ArCF_2X (Ar = CAFS, C_6H_5; X = Br, I ), with sodium dithionite took place readily in aqueous acetonitrile under mild conditions. giving the corresponding sodium sulfinate. The 1: 1 adducts were obtained when alkenes were added to the reaction system in some cases.The sulfinatodehalogenation reaction of α,α-difluorobenzyl handes, ArCF_2X (Ar = CAFS, C_6H_5; X = Br, I ), with sodium dithionite took place readily in aqueous acetonitrile under mild conditions. giving the corresponding sodium sulfinate.
