Abstract
The hexanuclear rhodium carbonyl, Rh6(CO)16, reacts with triphenylphosphine or triphenylarsine (L) to give hexanuclear derivatives of the type Rh6(CO)7L9 and with Ph2P·[CH2]2·PPh2(diphos) to give Rh6(CO)10(diphos)3. Reaction with thiols, halogens, or carboxylic acids gives mainly binuclear derivatives of the type Rh2(CO)4S2R2, Rh2(CO)4X6, and Rh2(CO)4(RCO2)2.
