ABSTRACT Disclosed herein is a process for preparing a corresponding cinnamate ester by reacting a styrene compound, carbon monoxide, an alcohol and oxygen by the use of (1) metallic palladium or a compound thereof, (2) a copper compound, (3) a compound of at least one metal selected from Groups 4A, 5A, 7A, 8A (the iron group only) and 2B in the Periodic Table and (4) a halogen compound as a catalyst which comprises treating the catalyst components recovered from the reaction liquid after completion of the reaction with an oxidizing agent in the presence of an organic acid to regenerate their catalytic activity, using the resulting catalyst components again in the reaction as a catalyst and repeating the foregoing procedure. The regenerated catalyst is recovered in catalytic activity to the extent of that of a fresh catalyst and thus gives a high reaction performance in the subsequent reaction. Thus, the catalyst contain- ing expensive metal can be used circulatively.
