Oxidative trifluoromethylation of unactivated olefins: an efficient and practical synthesis of α-trifluoromethyl-substituted ketones.

Abstract

An economical approach to α-CF3-substituted ketones, which are important intermediates in synthetic and medicinal chemistry, employs olefins and the readily available Langlois reagent (CF3SO 2Na). The reaction is operationally simple, proceeds at room temperature, and exhibits an excellent tolerance toward a wide variety of functional groups. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
