摘要：PURPOSE:To carry out practically and advantageously the isomerization reaction of quadricyclane with a faster reaction rate than other palladium complex catalysts by using cyclopropenylidene palladium complex as the isomerization reaction catalyst. CONSTITUTION:A catalyst which is useful for the isomerization reaction of quadricyclanes to norbornadienes is constituted from cyclopropenylidene palladium complexes shown by a formula (where R is H, lower alkyl group or cyano group; X is halogen atom). When the catalyst is applied to the isomerization reaction, it is used by dissolving it in a halogenated hydrocarbon such as chloroform. The amount of the catalyst to be used is generally 0.001-0.5mol per 1mol quadricyclane. By using this catalyst as the isomerization reaction catalyst, the faster reaction rate than other palladium complex catalyst is obtd., and the isomerization reaction of quadricyclanes is carried out practically and advantageously.
