Abstract
A convenient preparative route for synthesis has been developed and nicotinoyl isocyanates (NIC) have been obtained for the first time by the action of oxalyl chloride on amides of substituted nicotinic acids. A procedure has been found for suppressing the formation of hydrochlorides of nicotinoyl amides by the competing reaction of HCl with the initial amides of nicotinic acids. The special features of the fragmentation of nicotinoyl isocyanates under electron impact have been studied.
