Abstract

Abstract The reaction of cobalt hydrotetracarbonyl with acetylene was carried out in methanol as a model of the carboxylation of acetylene. The complexes formed in this reaction were identified by means of IR, NMR, EA and molecular weight measurement. The main product was acetylene dicobalt hexacarbonyl. From the decomposition reaction of this complex in ethanol, ethyl acrylate, ethyl propionate and diethyl succinate were obtained. The yield of ethyl acrylate increased in the presence of carbon monoxide. The reaction course from acetylene to acrylate was examined.
