Notes:
Phosphaalkynes, RC≡P (R = But, Adamantyl), add across the Rh=Rh double bond of [Rh2Cp2*(CO)2] to give either [Rh2Cp2*(μ-CO)(COPCR)] or [Rh2Cp2*(CO){PCRC(O)CRP}] depending on the stoichiometry of the reaction (Cp* = η5-C5Me5). The structures of these complexes have been elucidated by NMR spectroscopy and by a single crystal X-ray study on [Rh2Cp2*(CO){PCAdC(O)CPAd}]. Small amounts of the 1,3-diphosphacyclobutadiene complexes [RhCp*(P2C2R2)] and the trinuclear compound [Rh3Cp3*(CO)2] are also formed in these reactions. The reactions of RC≡P with [CoRhCp2*(CO)2] are also described.A preliminary account of part of this work has appeared in J. Chem. Soc., Chem. Commun., 1987, 658.
