Abstract

Fluorine-containing olefins are important synthetic intermediates for the biologically active compounds.'We have recently reported the transition metal induced synthesis of trifluoromethylated unsaturated carbonyl compounds. 2 In the reaction, CFsCCl $ radical is generated from CF3CC13 by single electron transfer from a Cu (1) or Ru (I1) salt and is used as the reactive intermediate for the addition to trimethylsilyl enol ethers to give ...
