Abstract

An effective and environmentally benign preparation of 2,2-dichloroaldehydes has been achieved by chlorination of aldehydes with Cl-2(g) in CH2Cl2, using 2,6-lutidine hydrochloride as recoverable catalyst. Remarkable qualities of the process are: easy work up, high purity products, HCl as the only 'waste' stream and inherent bias to the scale up. (C) 2000 Elsevier Science Ltd. All rights reserved.
