ABSTRACT:
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.
