Reactions of fluoro olefins

Summary

• 1. A perfluoroisobutene in which the fluorine atom in the 1-position is replaced by an alkoxy, alkyl, or aryl group reacts with amines and ammonia in the 1- or 3-position; the position attacked is determined both by the structure of the fluoro olefin and the character of the attacking reagent.

• 2. The reaction of such substituted perfluoroisobutenes with excess of aqueous ammonia leads to the complete elimination of fluorine from the molecule and the formation of derivatives of malononitrile.
