  Reactivity patterns of the unsaturated tetrahedral cluster [Re₄(µ₃-H)₄(CO)₁₂]. Easy addition of four MeCN molecules and ‘ionic’ or ‘neutral’ fragmentation pathways of the spiked-triangle intermediate [Re₄(µ-H)₄(CO)₁₂(NCMe)₄]

  摘要：

  The unsaturated (56 valence electrons, v.e.s) tetrahedral cluster [Re-4(mu(3)-H)(4)(CO)(12)] 1 readily added four acetonitrile molecules, affording two isomers 2a and 2b of the 64 v.e.s [Re-4(mu-H)(4)(CO)12- (NCMe)(4)] derivative, containing a spiked-triangle metallic skeleton. These isomers at room temperature rapidly underwent an ionic fragmentation to the known unsaturated triangular cluster anion [Re-3(mu-H)(4)(CO)(9)(NCMe)](-) and to the cation [Re(CO)(3)(NCMe)(3)](+). The rate of decomposition significantly increased at low [MeCN] concentration. Treatment of compounds 2a and 2b with the pi-acidic ligand CO, in the absence of free acetonitrile, gave only neutral products. Monitoring by NMR spectroscopy has revealed the rapid stepwise substitution of the nitrile ligands, accompanied by fragmentation to the known saturated triangular clusters [Re-3(mu-H)(3)(CO)(12-n)(NCMe)(n)] (n = 1-3) and to the mononuclear complexes [ReH(CO)(5-n)(NCMe)(n)] (n = 0 or 1). The novel, unstable. mononuclear hydride [ReH(CO)(4)(NCMe)] has been obtained by treatment of [ReH(CO)(5)] with Me(3)NO in acetonitrile and by reaction of [ReH2(CO)(4)](-) with CF3SO3H. in acetonitrile. In the presence of free acetonitrile, compounds 2a and 2b reacted with CO more slowly and gave both anionic and neutral triangular clusters.

  Oxidation of [Re3(μ-H)4(CO)10]− with CF3SO3H in acetonitrile gives the new complex Re3(μ-H)3(CO)10(NCMe)2. This contains a triangle of metal atoms with the edges bridged by the hydrides (mean ReRe 3.266 Å). The acetonitrile ligands, bound to two metals in a trans-diaxial manner, are easily replaced, giving a variety of derivatives.
