Stereoselective synthesis of trifluoromethylated α-chloro-α,β-unsaturated esters and nitriles
Abstract
A stereoselective synthesis of trifluoromethylated α-chloro-α,β-unsaturated esters and nitriles by the reaction of fluorinated ylide-anion resulting from nucleophilic addition of organolithium or Grignard reagents to trifluoromethylated phosphoranes with N-chlorosuccinimide is described.
