Abstract Several types of catalyst systems were examined in the olefin hydroalkoxycarbonylation reaction. The systems contained Pd (PPh 3) 4, PdCl 2 (PPh 3) 2, or some other palladium compounds as a principal component. The second component (promoter) was p-toluenesulfonic acid or diphenyl (m-sulfophenyl) phosphine, which combines both the ligand and promoter functions. An important feature of these systems is ...
