Abstract

Iodoarenes (iodobenzene and 2-iodothiophene) and iodoalkenes (1-iodocyclohexene, 1- iodo-4-tert-butylcyclohexene, 1-iodo-2-methylcyclohexene and 1-iodo-1-(1-naphthyl) ethene) were used as substrates in palladium-catalysed aminocarbonylation with N, O- dimethylhydroxylamine. The corresponding Weinreb amides were prepared in high isolated yields (up to 87%) when forcing conditions (40–60bar of CO, 50° C) were used. The ...
