The sulfinatodehalogenation reaction of α,α-difluorobenzyl halides,ArCF₂X (Ar=C₆F₅,C₆H₅; 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.
