The dicobalt octacarbonyl catalyzed reaction of hydridocobalt tetracarbonyl and ethyl acrylate in the presence of carbon monoxide results under kinetically controlled conditions (<10 °C) in the formation of ethyl propionate, ethyl 2-formylpropionate, and tetracarbonyl. Under thermodynamic control (>25 °C) the latter complex is transformed into (3-(ethoxycarbonyl)propionyl)cobalt tetracarbonyl which is the precursor of ethyl 3-formylpropionate. This temperature effect is in accordance with the known influence of temperature on the distribution of isomeric aldehydes in the catalytic hydroformylation of ethyl acrylate.
