Treatment of a series of α-thioamides with N-chlorosuccinimide results in efficient transformation to the analogous α-thio-β- chloroacrylamides. The mechanistic pathway has been established through isolation and characterisation of intermediate compounds. The scope of the transformation has been explored - aryl and alkylthio substituents, primary, secondary and tertiary amides can be employed. In most instances, the chloroacrylamides are formed exclusively as the Z-stereoisomer; however, with tertiary propanamides or with amides derived from butanoic or pentanoic acid a mixture of E- and Z-stereoisomers is formed.

α-Phenylthio secondary propanamides 1a-e are converted stereospecifically on treatment with NCS to the analogous (Z)-α-phenylthio-β-chloro propenamides 2a-e.Extension to longer chain secondary amide derivatives 1f-g is also possible, albeit less efficient
