1-(Hetero)aryl-2,2,2-trichloroethanols are useful key intermediates for the synthesis of various bioactive compounds. Herein, we describe N-heterocyclic carbene (NHC)-coordinated cyclometallated palladium complex (CYP)-catalyzed (hetero)aryl addition of chloral hydrate using (hetero)arylboroxines, providing a new approach to 1-(hetero)aryl-2,2,2-trichloroethanols.

Aromatically substituted acetic acids are prepared by the reaction of an aromatically substituted aldehyde with a combination of a trihalomethane and an alkanethiol, and by the reaction of an alcohol derivative (2,2,2-trihalo-1-arylethanol) with an alkanethiol, in the presence of a base in a mixed medium of water and an aprotic polar solvent.

An efficient synthesis of 2-imino-4-thiazolidinones from readily accessible alkyl (aryl) trichloromethylcarbinols and thioureas under mild conditions is reported. A one-pot three-component synthesis of the title compounds from aldehyde, chloroform and thiourea is also developed for the first time. (C) 2004 Elsevier Ltd. All rights reserved.
