Nucleophilic Trifluoromethylthiolation of Allylic Bromides: A Facile Preparation of Allylic Trifluoromethyl Thioethers

Authors


Abstract

A facile preparation of allylic trifluoromethyl thioethers was achieved by using a copper reagent. The reaction of (bpy)Cu(SCF3) with various allylic bromides afforded the desired trifluoromethylthiolation products in good to excellent yields with high stereo- and regioselectivity. Common functional groups such as alkyl, alkoxy, trifluoromethyl, nitro, halides and geranyl are well tolerated.
