  Electrophilic addition of selenium and telluriom halides to methyldiethynylsilane

  摘要：

  Regio- and stereoselective electrophilic addition reactions of SeCl2, SeBr2, SeCl4, SeBr4 to methyldiethynylsilane lead to predominant formation of the Z-isomers of 3,6-dihalo-4-methyl-1,4-selenasilafulvenes, disiloxanes on their bases, as well as disiloxanes formed upon the reaction with methyldiethynylsilane. TeCl4 reacts with methyldiethynylsilane with predominant formation of the E-isomer of 1,1,3,6-tetrachloro-1-methyl-1-(methyldiethynylsiloxy)-1,4-tellura(IV)silafulvene as a result of the reaction of the intermediate E-isomer of 4-methyl-1,1,3,6-tetrachloro-1,4-tellura(IV)silafulvene with methyldiethynylsilane. The structure of the products was proved by the methods of H-1, Se-77 NMR, IR spectroscopy and chromatomass spectrometry.
