  Hexacoordinate Silacyclobutane Dichelate Complexes: Structure, Properties, and Ligand Crossover

  摘要：

  Hexacoordinate dichelate silacyclobutane complexes have been synthesized from dichlorosilacyclobutrine and O-trimethylsilylated hydrazides by transsilylation. Like previously reported hexacoordinate silicon complexes, they readily and quantitatively undergo ligand exchange with other silicon compounds (XSiCl3 and differently substituted O-trimethylsilylated hydrazides), evidence that ionic dissociation does not play a significant role in the exchange mechanism. Germanium tetrachloride causes central-element exchange and formation of analogous hexacoordinate germanium complexes. Likewise, silicon tetrachloride replaces germanium from its hexacoordinate complexes, obeying certain selectivity constraints. When silicon complexes have strongly electron-withdrawing chelate-ring substituents (CF3 or CH2CN), GeCl4 causes, in addition to central-element exchange, also oxidative opening of the four-membered ring and addition of two chlorine atoms. Both chelate exchange and central-element exchange are shown to be dominated by monodentate ligand priorities.

  of hypercoordinate silicon(IV) complexes are synthesized by the reactions of O-silylated N,N-dimethylhydrazides with YSiCl3 (Y = cyclohexyl and i-Bu). All the complexes are characterized by 1H, 13C, and 29Si-NMR spectroscopy. The influence of steric and electronic behavior of remote substituents and the groups attached to silicon on the methyl halide elimination reactions of these complexes are discussed
