HYDROFORMYLATION OF OLEFINS CATALYZED BY HOMOGENEOUS HETERONUCLEAR METAL CLUSTER [PhCH_2Me_3N][FeCo_3(CO)_(12)]

Hydroformylation of olefins catalyzed by heteronuclear metal cluster [PhCH_2Me_3N]-[FeCo_3(CO)_(12)] was studied. The effect of temperature, pressure, and solvent ect. on olefin hydroformylation was examined. The results show that for the hydroformylation of various olefins, e.g. 1-hexene, isobutene, 2-octene, cyclohexene, diisobutene, and styrene, the Fe-Co cluster exhibits rather high activity under mild conditions. For example, under the pressure such of 4 MPa, H_2/CO ratio of 1: 1, at 120℃, 1-hexene was hydroformylated to heptanal with the conversion of > 80％ and the selectivity of > 95％ in 1 hr.
