Abstract
Colloidal rhodium particles, photochemically generated from Rh-4(CO)(1 2), via transfer hydrogenation, photochemically catalyzed the transfor mation of 1,5-cyclooctadiene (1,5-COD) to cyclooctene (COE) and then t o cyclooctane (COA) in the presence of acetone, a triplet sensitizer, and 2-propanol, a hydrogen donor. The hydrogenation rate of 1,5-COD wa s faster than that of COE by a factor of 4.3. Maximum selectivity of C OE was found to be 85%.
