Question

Why hexafluoroacetone is used in epoxidation reaction?

Answer 1

Hexafluoroacetone is a reactive electrophile. It reacts with activated aromatic compounds (e.g., phenol), and can be condensed with olefins, dienes, ketenes, and acetylenes. ... The industrial importance of HFA arises largely from its use in polymers and as an intermediate in monomer synthesis.
