    Reactivity of the unsaturated dimolybdenum anion [Mo2(η5-C5H5)2(μ-PCy2)(μ-CO)2]− towards electrophiles based on p- and d-block elements
    摘要:
    The 30-electron binuclear anion [Mo2Cp2(mu-PCy2)(mu-CO)(2)] reacts with the chlorophosphite ClP(OEt)(2) or the organotin chlorides Cl2SnPh2 or ClSnPh3 to give compounds of the formula trans-[Mo2Cp2-( mu-E)(mu-PCy2)(CO)(2)], (E = P(OEt)(2), SnPh3, SnPh2Cl). In contrast, this anion reacts with the organosilicon chlorides ClSiR3 (R = Ph, Me) to give unstable silyloxycarbyne-bridged complexes [Mo2Cp2(mu-PCy2)-( mu-COSiR3)(mu-CO)], which rapidly hydrolyze to give the known hydride [Mo2Cp2(mu-H)(mu-PCy2)(CO)(2)]. Two main types of products were also observed in the reactions of the title anion with different chlorocomplexes of the transition and post-transition metals. Thus, the reactions with [MCl2Cp2] (M = Ti, Zr) give moisture-sensitive isocarbonyl-bridged complexes of the type [Mo2Cp2(mu-COM-ClCp2)( mu-PCy2)(mu-CO)]. In contrast, softer metallic electrophiles such as [AuCl(PR3)] (R = Pr-i, ptol) react with the anion at the dimolybdenum site to form new trimetallic clusters of the formula [AuMo2Cp2-( mu-PCy2)(CO)(2)(PR3)], also retaining a Mo Mo triple bond. Subsequent reactions of the latter products with the solvate complexes [Au(PR3)(THF)][PF6] give the tetranuclear clusters [Au2Mo2Cp2(mu-PCy2) (CO)(2)(PR3)(2)][PF6] (Mo-Mo = 2.5674(3) angstrom and Au-Au = 2.7832(2) angstrom when R = Pr-i). Finally, the reaction of the title anion with HgI2 gives the pentanuclear cluster [Hg{Mo2Cp2(mu-PCy2)(CO)(2)}(2)] or the trinuclear cluster [Mo2Cp2(mu-HgI)(mu-PCy2)(CO)(2)] depending on the stoichiometry being actually used for the reaction. The trinuclear species is only stable in tetrahydrofuran (THF), and decomposes to give a mixture of the dimeric species [Mo2Cp2(mu-HgI)(mu-PCy2)(CO)(2)](2) along with variable amounts of the known iodide-bridged complex [Mo2Cp2(mu-I)(mu-PCy2)(CO)(2)].

The latter reacts with Mel and ClSnPh3 through a single P atom to give respectively diphosphenyl [Mo2Cp2(mu-PCy2)(CO)(2)(mu-kappa(2):kappa(2)-P2Me)] (3) and stannyl [Mo2Cp2(mu-PCy2)(CO)(2)mu-kappa(2):kappa(2)-P-2(SnPh3)}] (4) derivatives, with the P-P-Sn angle in 4 being unexpectedly acute [80.3(1)degrees]. According to density functional theory calculations, this novel nucleophilic behavior of is derived from its anionic nature, thus enabling the P-2 ligand to act in a pi-donor-like fashion.
