  Conversion of the clusters [Os3(1,3-diyne)(CO)10] into bis(alkynyl) clusters by carboncarbon bond cleavage

  摘要：

  The symmetrical 1,3-diynes, RC(2)C(2)R (R=Me, Et, Ph, Bu(t), SiMe(3),), react with [Os-3,(CO)(10)(MeCN)(2)] to give the clusters [Os-3(mu(3),eta(2)-RC(2)C(2)R)(mu-CO)(CO)(9)]. The mu(3),eta(2)-coordinated alkyne group does not exchange with the non-coordinated one. As a consequence the unsymmetrical diyne, PhC(2)C(2)SiMe(3), gives non-interconverting and separable isomers of [Os-3(mu(3) eta(2)-PhC(2)C(2)SiMe(3))(mu-CO)(CO)(9)] which differ only in which of the two alkyne groups is coordinated. Thermal decarbonylations of the compounds containing RC(2)C(2)R (R=Ph, Bu(t) or SiMe(3)) and the isomers containing the unsymmetrical diyne, PhC(2)C(2)SiMe(3), lead by carbon-carbon bond cleavage to bis(alkynyl) dusters of the type [Os-3(mu(2) eta(1)-C(2)R(2))(mu(3),eta(2)-C(2)R(2))(CO)(9)] where R(1)=R(2)=Ph, Bu(t) SiMe(3) and only one isomer from the mixed diyne with R(1)=Ph and R(2)=SiMe(3). XRD studies on this isomer established that C(2)SiMe(3) is in the triply-bridging position and C(2)Ph in the doubly-bridging position. Although the C(2)Ph ligand is only bonded through the alpha-carbon atom, we consider it to be alpha, pi-bonded and a three-electron donor. It spans two osmium atoms that are not bonded (Os...Os=3.297(2) Angstrom). Thermolysis of the EtC(2)C(2)Et complex leads to carbon-hydrogen rather than carbon-carbon cleavage to give the allenyl cluster [Os3H(mu(3),eta(2),eta(2)-MeCH=C=C-C(2)Et)(CO)(9)], while the MeC(2)C(2)Me cluster decarbonylates to [Os-3(C(4)Me(2))(CO)(9)] of unknown structure but which may be [Os-3(CMe)-(CC(2)Me)(CO)(9)].
