Abstract

Low temperature in situ UV irradiation of [(η5-C5H5)Co(C2H4)2] in the presence of silanes enables the characterisation of unstable fluxional Co(III) silyl hydride complexes [(η5-C5H5)Co(SiR3)(H)(C2H4)] (SiR3 = SiEt3, SiMe3 or SiHEt2) by NMR spectroscopy; the reaction of [Co(η5-C5H5)(C2H4)2] with HSiR3 proceeds thermally to reach an equilibrium when SiR3 = Si(OMe)3 or SiClMePh.
