4-cyclohexene-1,2-dicarboxylic acid anhydride is dissolved in three times the amount of dimethyl formamide, and an equimolar quantity of acetonitrile palladium dichloride is added in the course of 2 hours at 40° C. Dimethylformamide and acetonitrile are distilled off at 45° C./25 mbar. A brownish solid melting at from 53° to 54° C. is obtained in 90% yield. Isobutyl vinyl ether palladium dichloride is prepared analogously from acetonitrile palladium dichloride and isobutyl vinyl ether, melting point 57°-60° C.
