Direct Synthesis of the Perfluoroalkanesulfinates of Iron(II), Cobalt(II), and Nickel(II): SO2‐Assisted Addition of Alkyl Halides to Transition Metals

Abstract

Reactions of typical transition metals with alkyl halides normally take place only after prior chemical or physical activation of the metals. It is now possible to bring about reaction of commercial grade Fe, Co, and Ni powder with perfluoroalkyl iodides (RI) under mild conditions: In the presence of SO2, the alkanesulfinates (1) with a dinuclear cation are formed in dimethylformamide at room temperature.
