Tetrahydrophthalic anhydride → Vinyl isobutyl ether

Participants

Reaction Steps

4-cyclohexene-1,2-dicarboxylic acid anhydride is dissolved in three times its quantity of dimethyl formamide. Its equimolar quantity of acetonitrile palladium dichloride is added at 40° C. in the course of 2 hours. Dimethyl formamide and acetonitrile are distilled off at 45° C./25 mbar. A brownish solid with a melting point of 53°-54° C. is obtained in a 90% yield. Isobutylvinyl ether palladium dichloride is obtained in analogous manner from acetonitrile palladium dichloride and isobutyl vinyl ether, melting point 57°-60° C.
