COBALT(II) CHLORIDE AND BIS(ACETYLACETONATO)COBALT(II)-SODIUM BIS(2-METHOXYETHOXY)ALUMINUM HYDRIDE (SMAH) SYSTEMS: CONVENIENT CATALYSTS FOR HYDROGENATION

The titled catalyst systems were found to be active and convenient for the hydrogenation of olefins and to be selective toward 1,3-COD. The catalyst was transformed to some extent during the hydrogenation of 1,3-COD: cyclooctene was formed preferentially and thereafter was hydrogenated to cyclooctane successfully.
