Unprecedented effects of the trimethylsilyl group on the reactivity of 3C-silylated silacyclopentenes and their derivatives

We have synthesised new 3C-silylated silacyclopentenes from the corresponding 3-trimethylsilyl-1,1-dichloro-1-silacyclopent-3-enes. The presence of two metal centres M (M = Si) in α and β-positions confers an original structure for these new heterocycles. The chemical behaviour of such compounds and their derivatives was studied and compared to the results obtained in the non-substituted silacyclopentane series.

MISE EN EVIDENCE DE LA FORMATION DE R2M=MR2 A PARTIR DE DISILA-1,2 ET DIGERMA-1,2 CYCLOHEXENES-4

Intermediates with ?-bonded Si or Ge are generated during gas phase pyrolysis of 1,2-disila- or 1,2-digerma-cyclohex-4-enes. Compounds such as R2M=MR2 are successfully trapped by addition or and cycloadditions.These results were proved by mass spectrometry.
