Novel Reactions of Perfluoro‐2‐(trifluoromethyl)propene.

Abstract Unlike its hydrocarbon counterpart, perfluoro-2-(trifluoromethyl)propene is a highly reactive compound. It participates in both heterolytic and homolytic reactions. It readily reacts with nucleophiles and sluggishly with electrophiles. It reacts as well with common organic solvents, such as dimethylformamide, ethanol and others. In this communication, we describe its reactions with trifluoromethylthiocopper, sulfur trioxide and tributyltin cyanide, the mechanism of formation of the various products and their mass spectral data.
