Catalyst for the isomerization reaction of quadricyclanes to norbornadienes

摘要

The present invention relates to a catalyst for the isomerization reaction from quadricyclanes to norbornadienes in a conversion system from light energy to heat energy which comprises cyclopropenylidene palladium complex represented by the formula, <IMAGE> wherein R represents hydrogen atom, a lower alkyl or cyano group and X represents a halogen atom, and further relates to a fixed catalyst for the isomerization reaction from quadricyclanes to norbornadienes in a conversion system from light energy to heat energy which is obtained by adsorption-fixing a porphyrin Co(II) complex represented by the formula, <IMAGE> wherein R2 represents a lower alkyl group and R3 represents a hydroxycarbonyl lower alkyl group, to a modified inorganic carrier in which a polyamine sulfone comprising a recurring unit represented by the formula, <IMAGE> wherein R1 represents a lower alkyl group and X represents a halogen atom, has been adsorbed on a solid inorganic carrier.
