^§ These authors contributed equally to this work.

Abstract

A facile procedure for the copper-mediated oxidative trifluoromethylthiolation of potassium aryl- and heteroaryltrifluoroborates with Ruppert–Prakash reagent and elemental sulfur is presented. Aryl trifluoromethyl thioethers can be prepared in good to moderate yield under mild reaction conditions.

Key Words

aryl trifluoromethyl thioethers - trifluoromethylthiolation - potassium aryltrifluoroborates - copper - Ruppert–Prakash reagent - elemental sulfur
