Zusammenfassung:A process for preparing an alpha -substituted cyanoacetic acid alkyl ester which comprises contacting an unsaturated nitrile of the formula I wherein R2 is a hydrogen atom or a methyl group and R3 is CH2, CHCH3, CHCN, CHC6H5 or C(CH3)2 with an alcohol of the formula ROH II wherein R is a primary, secondary or tertiary saturated alkyl moiety of 1 to 20 carbon atoms and carbon monoxide in the presence of Co2(CO)8 and an alpha -substituted pyridine in the absence of hydrogen at an elevated temperature and pressure.
