Abstract

The hydroformylation-amidocarbonylation of a fluoro olefin, C//6F//5CH equals CH//2, catalyzed by Co//2(CO)//8-rhodium carbonyl systems proceeds with excellent regioselectivity. The process includes a unique Co-Rh mixed-metal complex, CoRh(CO)//7, as an active catalyst species whose presence is revealed by the high-pressure IR study in the actual reaction system. The mechanism of this novel mixed-metal complex catalyzed process is discussed. The relative catalytic activities of CoRh(CO)//7, rhodium carbonyl, and cobalt carbonyl are estimated on the basis of the kinetic measurements as well as the analysis of regioselectivities attained by these three catalyst species.
