  Wagner–Meerwein-Type Rearrangements of Germapolysilanes - A Stable Ion Study

  摘要：

  The rearrangement of tris(trimethylsilyl)silyl-trimethylgermane 1 to give tetrakis(trimethylsily)germane 2 was investigated as a typical example for Lewis acid catalyzed Wagner-Meerwein-type rearrangements of polysilanes and polygermasilanes. Direct Si-29 NMR spectroscopic evidence is provided for several cationic intermediates during the reaction. The identity of these species was verified by independent synthesis and NMR characterization, and their transformation was followed by NMR spectroscopy.

  Syntheses and Photochemically Induced Rearrangements of Tetrasilyl- and Trisilylgermyl Complexes of Iron:  (η⁵-C₅R₅)Fe(CO)₂(SiMe₂)₃EMe₂Ph (R = H, Me; E = Ge, Si)

  摘要：

  Oligosilyl and oligosilylgermyl complexes (eta(5)-C5R5)Fe(CO)(2)(SiMe2)(3)EMe2Ph (R = H (1), Me (2); E = Ge (a), Si (b)) have been synthesized, characterized, and photolyzed. All complexes isomerized cleanly to (eta(5)-C5R5)Fe(CO)(2)E(SiMe3)(2)(SiMe2Ph). Photolysis of a mixture of (eta(5)-C5Me5)Fe(CO)(2)(SiMe2)(3)GeMe2Ph (2a) and (eta(5)-C5H5)Fe(CO)(2)(SiMe2)(3)SiMe3 (1b) proved that the rearrangements occur via an intramolecular mechanism. Irradiation of 1 and 2 in the presence of HMPA resulted in the formation of (eta(5)-C5R5)Fe(CO)(=SiMe2. HMPA)(SiMe2-SiMe2EMe2Ph), indicating that silylene intermediates are key to the rearrangements. Attempts to use this new chemistry to perform the catalytic isomerization Me3GeSiMe2-SiMe2SiMe2H --> (Me3Si)(3)GeH resulted in high yields of (Me3Si)(3)GeSiMe2H. This product indicates the ability of (Me3Si)(3)GeH to intercept the Fe-silylene intermediates.

  The base-stabilized silylene complex (eta (5)-C5H5)Fe(CO)(eta (2)-SiMe2-(OBu)-Bu-t-SiMe2) is unreactive toward (Me3Si)(3)EH (E = Si, Ge) under photochemical irradiation or at room temperature. However, at 80 degreesC it reacts, presumably via the equilibrium concentration of base-free complex (eta (5)-C5H5)Fe(CO)((SiMe2OBu)-Bu-t)(=SiMe2), to transfer the silylene group and form (Me3Si)(3)ESiMe2H. Attempts to transfer the SiMe2 group to tributyltin hydride led to formation of bis(tributylstannyl)iron completes.
