  Synthesis of Novel Metal−Germavinylidene Complexes from Bisgermavinylidene

  摘要：

  The bisgermavinylidene [(Me3SiN=PPh2)(2)C=Ge -> Ge=C(PPh2=NSiMe3)(2)] (1) has been used as the source of unstable germavinylidene for the synthesis of a series of metal-germavinylidene complexes. Treatment of 1 with M(PPh3)(4) (M = Ni, Pd) afforded the metal-germavinylidene complexes [{(Me3SiN=PPh2)(2)C=Ge}(2)Ni(PPh3)2] (2) and [{(Me3SiN=PPh2)(2)C= Ge-mu(2)}Pd(PPh3)](2) (3), respectively. The germavinylidene moiety from 1 acts as a two-electron terminal and bridging ligand, respectively. Similar reaction of I with AgCl or AuI gave [(Me3SiN=PPh2)(2)C=Ge(Ag)(Cl)](2) (5) and [(Me3SiN=PPh2)(2)C=Ge(Au)(I)](2) (6), respectively. The result has shown that the germavinylidene moiety from I behaves as a Lewis base and undergoes an insertion reaction into the metal-halogen bond. X-ray structures of 2, 3, 5, and 6 have been determined.

  Synthesis of Bisgermavinylidene and Its Reaction with Chalcogens

  摘要：

  The lithium complex [HC(PPh2=NSiMe3)(2)Li(THF)] (2) prepared by the reaction of (BuLi)-Li-n with bis(iminophosphorano)methane reacts with GeCl2.dioxane in different stoichiometric ratios to afford [HC(PPh2=NSiMe3)(2)GeCl] (3) and [(Me3SiN=PPh2)(2)C=Ge-->Ge C(PPh2=NSiMe3)(2)] (4), respectively. Bisgermavinylidene 4 can also be obtained by the reaction of 3 with [Ge{N(SiMe3)(2)}(2)] or 2. Further reaction of 4 with Me3NO afforded [(mu-N=Ph2P)(Me-3-SiN=Ph2P)C=Ge(OSiMe3)](2) (5), and direct reaction of elemental chalcogens (sulfur, selenium, and tellurium) with 4 afforded [(Me3SiN=PPh2)(2)C=Ge(mu-E)](2) [E = S (6), Se (7), and Te (8)]. X-ray structures of compounds 2-8 have been determined.

  Bisgermavinylidene [(Me3SiN=PPh2)(2)C=Ge -> Ge=C(PPh2=NSiMe3)(2)] (1) has been used as a source of unstable germavinylidene for the synthesis of a series of heterobinuclear complexes. The reaction of 1 with stoichiometric amounts of transition metal chlorides MCl2 (M = Mn, Fe) yielded [(Me3SiN=PPh2)(2)(GeCl)CMn(mu-Cl)](2) (2) and [(Me3SiN=PPh2)(2)(GeCl)CFeCl] (3), respectively. Treatment of 1 with Me3SiN3, gave the [2 + 3] cycloaddition product [(Me3SiN=PPh2)(2)CGeN(SiMe3)N=N] (4). While similar reaction of 1 with (Bu-n)(3)SnN3 (Bu-n = n-butyl) and water-borane adduct H2O -> B(C6F5)(3) afforded the 1,2-addition products [(Me3SiN=PPh2)(Bu-n)(3)Sn}CPPh2NSiMe3GeN3] (5) and [HC(PPh2=NSiMe3)(2)Ge(OH)B(C6F5)(3)] (6), respectively. The results suggested that the germanium-carbon bond in germavinylidene is capable of forming addition reaction products. The X-ray structures of 2-6 have been determined.

  Low-valent metallavinylidenes :M=C/\ are scarce owing to the low stability of such species. Compound 1, prepared from [CH(Ph2 P=NSiMe3 )2 Li(thf)] and GeCl2 ⋅dioxane, represents the first stable bis(germavinylidene). The dimetallacyclobutanes 2 (M=Pb, Sn) were also prepared-they are believed to form by dimerization of the intermediate metallavinylidenes.
