ABSTRACT:
A homogeneous catalytic process for the decarbonylating of formate esters to alcohols and carbon monoxide. The process comprises contacting formate esters of the formula HCOOR where R is C.sub.1 -C.sub.10 aliphatic, C.sub.7 -C.sub.14 araliphatic or C.sub.6 -C.sub.10 aryl with a copper complex of the formula Cu(L)X where L is CO, phosphine or phosphite and X is the anion of an acid in an inert atmosphere at temperatures of from about 100.degree. to 300.degree. C.
