DIALDEHYDE COMPOUND, POLYMER, EPOXY RESIN, POLYESTER RESIN, AND POLYCARBONATE RESIN

The present invention provides a novel dialdehyde compound having a norbornane skeleton and a cyclohexanedione skeleton, a polymer, an epoxy resin, a polyester resin, and a polycarbonate resin industrially using a simple and economical method. A dialdehyde compound represented by formula (1) is formed by subjecting carbon monoxide and hydrogen gas to a hydroformylation reaction with a diene compound represented by formula (2) in the presence of a rhodium catalyst or a cobalt catalyst and an organic phosphorus compound. 本发明在工业上利用简单且经济性优异的方法提供具有降冰片烷骨架与环己二酮骨架的新颖的二醛化合物、聚合物、环氧树脂、聚酯树脂及聚碳酸酯树脂。通过在铑催化剂或钴催化剂及有机磷化合物存在下使一氧化碳及氢气与式(2)所表示的二烯烃化合物进行氢甲酰化反应的步骤而形成式(1)所表示的二醛化合物。
