Difluoro(trimethylsilyl)acetonitrile: Synthesis and Fluoroalkylation Reactions

A new silicon reagent, difluoro­(trimethylsilyl)­acetonitrile, was prepared by insertion of difluorocarbene into silyl cyanide. The obtained silane served as a good cyanodifluoromethylating reagent toward aldehydes, <i>N</i>-tosylimines, <i>N</i>-alkylimines, and enamines under basic or acidic conditions
