Abstract
This invention provides a process for stabilizing a phosphite ligand against degradation in a homogeneous reaction mixture containing a Group VIII transition metal catalyst and the phosphite ligand, said process comprising adding to the reaction mixture an epoxide in an amount from 0.001 to 5 weight percent based on the total weight of the reaction mixture to reduce the degradation of the ligand.
