Abstract
A direct intermolecular cross‐benzoin‐type condensation catalyzed by an N‐heterocyclic carbene has been developed. The cross‐coupling of commercially available aromatic aldehydes and trifluoromethyl ketones results in α‐hydroxy‐α‐trifluoromethyl ketones bearing a quaternary stereocenter with excellent chemoselectivity and good to excellent yields.Keywords
