Iridium and rhodium perfluorobenzenethiolato complexes. Syntheses and catalytic behavior
摘要:
By reacting [(C5Me5)M(SRF)(2)] (for M = Ir, R-F = C6F5 (1a) or C6F4H-p (1b); for M = Rh, R-F = C6F5 (2a) or C6F4H-p (2b)) in toluene with L (L = CO and PPh3), mononuclear compounds with the general formula [(C5Me5)M(SRF)(2)(L)] (for M = Ir and L = CO, R-F = C6F5 (3a) or C6F4H-p (3b); for M = Ir and L = PPh3, R-F = C6F5 (4a) or C6F4H-p (4b); for M = Rh and L = CO, R-F = C6F5 (5a) or C6F4H-p (5b); for M = Rh and L = PPh3, R-F = C6F5 (6a) or C6F4H-p (6b)) can be obtained. The [(C5Me5)M(SRF)(2)] 1a and 1b systems have been studied as catalyst precursors for the hydrogenation of cyclohexene in 2-propanol at 5 and 30 bar at 40 degrees C; 2a and 2b systems were studied in the presence of PPh3 as catalyst precursors for the hydroformylation of 1-hexene in toluene at 5 and 30 bar at 80 degrees C.
