Abstract
Some complexes prepared in situ from Co2(CO)8 and various di(tertiary phosphine)s as ligands have been found to be more active than Co2(CO)8 for the hydroformylation of methyl acrylate. The activity decreased in the order; Ph2P(CH2)2PPh2>Ph2PC≡CPPh2>cis-Ph2PCH=CHPPh2>Ph2P(CH2)3PPh2>none>Ph2PCH2PPh2>Ph2P(CH2)4PPh. The most active catalyst (I) was obtained when a molar ratio of Ph2P(CH2)2PPh2 to Co2(CO)8 was ca. 0.5. The catalyst (I) is also active even at low pressure, where the decomposition of Co2(CO)8 occurs.Keywords
