Carbon-hydrogen bond activation of phenyldi(2-thienyl)phosphine at a triosmium cluster centre

Summary, in English

The phenyldi(2-thienyl)phosphine (PhPTh2) complexes [Os-3(CO)(12-n)(PhPTh2)(n)] (n = 1-3) (1-3) have been prepared. Thermolysis of 1 and either 2 or 3 in octane affords carbon-hydrogen bond activation products [Os-3(CO)(9){mu(3)-PPhTh(C4H2S)}(mu-H)] (4) and [Os-3(CO)(8)(PPhTh2){mu(3)-PPhTh(C4H2S)}(mu-H)] (5), respectively. Both exist as isomeric mixtures differing in the relative positions of phenyl and thienyl substituents with respect to the triosmium centre. The nature of the process has been confirmed by a single crystal X-ray diffraction analysis of 4. (C) 2010 Elsevier B.V. All rights reserved.
