We present α-chloro amides as a new class of α-acetyl radical precursors, which undergo a tin-free, photoredox-catalysed intermolecular α-alkylation with various olefins exclusively in an anti-Markovnikov fashion. The reaction represents a reductive atom

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.
