Low temperature in situ UV irradiation of [(eta 5-C5H5)Co(C2H4)2] in the NMR probe: formation of Co(III) silyl hydride complexes.
Low temperature in situ UV irradiation of [(eta(5)-C(5)H(5))Co(C(2)H(4))(2)] in the presence of silanes enables the characterisation of unstable fluxional Co(III) silyl hydride complexes [(eta(5)-C(5)H(5))Co(SiR(3))(H)(C(2)H(4))] (SiR(3) = SiEt(3), SiMe(3) or SiHEt(2)) by NMR spectroscopy; the reaction of [Co(eta(5)-C(5)H(5))(C(2)H(4))(2)] with HSiR(3) proceeds thermally to reach an equilibrium when SiR(3) = Si(OMe)(3) or SiClMePh.
