✦ Synopsis

A Novel Efficient Synthesis of Heteroaryl Substituted α,β-Unsaturated Trifluoromethyl Ketones.

-The novel electrophilic reagent (IV), easily prepared by reaction of phenyl vinyl sulfide and trifluoroacetic anhydride followed by oxidation with peroxytrifluoroacetic acid, reacts with electron-rich heteroarenes to form E-isomers of α,β-unsaturated CF 3 ketones. -(NENA-
