Procedure

The promoters or rate enhancers added to the palladium catalyst are group VIB cabonyls. Such carbonyls are, for example, chromium hexacarbonyl, molybdenum hexacarbonyl and tungsten hexacarbonyl. The carbonyl promoter can be added to the reaction mixture or formed in situ. The chromium carbonyl gives greater catalyst enhancement than either molybdenum or tungsten. The amount of group VIB carbonyl added is from about 0.05 weight percent to 10 weight percent based on the weight of palladium used as the catalyst.
