Studies on organic fluorine compounds. IL The ene reaction of trifluoroacetone.

Abstract

The ene reaction of 1, 1, 1-trifluoroacetone with various olefinic compounds proceeded in the presence of aluminum chloride at low temperature to give allylmethyl (trifluoromethyl)carbinols. Olefinic compounds with a terminal vinyl group reacted smoothyl, but some olefins with an inner double bond did not react at all. Trifluoroacetone was also found to undergo a Friedel-Crafts type reaction with aromatic compounds.
