【Abstract】 Some cobolt and nickel complexes containing phosphine ligands have beed synthesized by the authors. The phosphine ligands include 2-(diphenylphosphino) pyridine,triphenylphosphine, tri-p-methylphenylphosphine, bis (diphenylphosphino-) methane and bis (diphenylphosphino-) ethane. The catalytic properties of these complexes for carbonylation of ethyl alcohol to ethyl propionate have been investigated and the effects of them on the catalytic reaction have been compared.更多还原
