Reaction of <2> (arene = C6H6, 1,4-MeC6H4CHMe2) with NaNH2 in CH3CN gives a dark oil which upon treatment with ROH/NaBPh4 (R = Me, Et) gives the triple bridged complexes (BPh4>.The structure of the benzene complex (R = Me) has been verified by X-ray analysis.The crystals are monoclinic, space group P2₁/n with a 11.725(4), b 15.573(5), c 18.739(2) Angstroem; β 103.29(2)deg.These complexes undergo reactions with tertiary phosphines and hydrogen halides.There is also spectroscopic evidence for intermolecular exchange of the bridging alkoxo ligands on mixing pure solutions of the ⁺ cations (M = Ru, Os).Reaction of <2> with Pb(SEt) 2 in CH3CN gives the analogous ⁺ cations.
