A new method has been developed for the synthesis of the ethyl ester of the mononitrile of malonic acid by the carbonylation of benzenesulfonyloxyacetonitrile in absolute ethanol in the presence of cobalt carbonyl.The yield of the desired product was 30 percent with 60-90percent conversion of the starting compound.The effects of temperature, pressure, and reaction time was studied. Keywords: carbonylation, dicobalt octacarbonyl, benzenesulfonyloxyacetonitrile, ethyl ester of the mononitrile of malonic acid.
