Addition of Organocuprates to Acetylenic Di- and Trifluoromethyl Ketones. Regiospecific Synthesis of β,β-Disubstituted Unsaturated Fluoro ketones

Article abstract of DOI:10.1021/jo00261a006

A regiospecific synthesis of β,β-disubstituted-α,β-unsaturated di- and trifluoromethyl ketones has been achieved by the conjugate addition of higher order cyano cuprate reagents to acetylenic di- and trifluoromethyl ketones.An efficient and reproducible s
