Abstract

The closo carbaborylmonophosphine 1-PPh₂-2-Ph-1,2-closo-C₂B₁₀H₁₀ is deboronated by reaction with ClAuPPh₃ in refluxing ethanol to afford the zwitterionic compound 7-{PPh₂AuPPh₃}-8-Ph-7,8-nido-C₂B ₉H₁₀, characterised by NMR spectroscopy and X-ray crystallography. Deprotonation of this species using NaH in THF followed by reaction with either [(p-cymene)RuCl₂]₂ or [(?-C₅Me₅)RhCl₂]₂ yields the compounds 1-{PPh₂AuCl}-2-Ph-3-(p-cymene)-3,1,2-RuC₂B ₉H₉ and 1-{PPh₂AuCl}-2-Ph-3-(?-C₅Me ₅)-3,1,2-RhC₂B₉H₉, respectively. These latter products, which on the basis of ¹¹B-NMR spectroscopy and (in the first case) a single crystal diffraction analysis, have pseudocloso structures, are the first reported examples of compounds in which a carbaborylphosphine ligand is ?⁵-bonded to a transition metal.
