Olefins and acetylenes are carbonylated to a carboxylic acid or ester using a homogenous catalyst system comprising palladium together with iron or a metal of Groups IVA, VA or IIIB, the catalyst being either a polynuclear complex incorporating both metals, or a mixture of a soluble palladium salt and metal halide. Starting with cyclic di-olefins, such as cyclo-octadiene, the product cycloalkenyl carboxylic acid or ester may be cleaved to give acyclic dicarboxylic acids, such as azelaic acid.
烯烃和乙炔可以使用由钯和铁或IVA、VA或IIIB族金属组成的均相催化剂系统进行羰基化反应,生成羧酸或酯。催化剂可以是包含两种金属的多核配合物,也可以是可溶性钯盐和金属卤化物的混合物。从环状二烯开始,如环辛二烯,产物环烯基羧酸或酯可以被裂解为无环二羧酸,如癸二酸。
