Transition metal–carbon bonds. Part XIII. Di-µ-chlorodicarbonyldi-(ethylene)dirhodium(I)
Abstract
[Rh2Cl2(CO)4] and [Rh2Cl2(C2H4)4] react in benzene solution to give [Rh2Cl2(CO)2(C2H4)2] in good yield. [Rh2Cl2(CO)2(C2H4)2] reacts with hydrogen chloride to given an ethylrhodium(III) complex [RhCl2Et(CO)]x which in turn reacts with dimethylphenylphosphine to give [RhCl2Et(CO)(PMe2Ph)2]. Nuclear magnetic resonance and infrared data are given.
