EXAFS INFRARED AND KINETIC-STUDIES ON A RUTHENIUM CARBONYL HYDROFORMYLATION SYSTEM

Abstract Alkali metal halides and iodine are effective promoters for ethylene hydroformylation catalysis by ruthenium carbonyls in basic media; the major species is [HRu 3 (CO) 11 ] t− characterized by IR and Ru K-edge EXAFS, but kinetic studies indicate that mononuclear and possibly, dinuclear fragments are responsible for the catalytic activity.
