Procedure

The reaction and analysis were carried out in the same manner as described in Example 12 except that 1.4 g of vinylmethyl ketone was used instead of methyl acrylate and the reaction time and temperature were adjusted to 7 hours and 220° C., respectively. It was confirmed that 0.433 g of benzalacetone and 0.167 g of benzylacetone were formed. The yields of benzalacetone and benzylacetone were 2970% and 1130%, respectively, based on the Rh atom. Identification of the products was performed by comparison with the standard substances with respect to the retention time in GC.
