Graphical Abstract

The more the merrier: Described is the direct synthesis of aryl bis(trifluoromethyl)carbinols from aryl bromides and fluorosulfates with a stoichiometric amount of carbon monoxide and two equivalents of trifluoromethyltrimethylsilane. The method exhibits good yields, broad scope, and good functional-group tolerance, and is suitable for carbon-isotope labeling.

Abstract

A palladium-catalyzed carbonylative approach for the direct conversion of (hetero)aryl bromides into their α,α-bis(trifluoromethyl)carbinols is described, and it employs only stoichiometric amounts of carbon monoxide and trifluoromethyltrimethylsilane. In addition, aryl fluorosulfates proved highly compatible with these reaction conditions. The method is tolerant of a diverse set of functional groups, and it is adaptable to late-stage carbon-isotope labeling.
