Ammonolysis of 1,2-bis[dichloro(methyl)silyl]ethane. on the structure of 1,3,6,8-tetramethyl-2,7,11,12-tetraaza-1,3,6,8-tetrasila-tricyclo[6.2.1.1 ~(3,6)]-dodecane

摘要

Ammonolysis of 1,2-bis[dichloro(methyl)silyl]ethane afforded a crystalline tricyclic silazane along with polymeric material. The crystalline material could be isolated in pure state. It was analyzed by ~1H, ~(13)C, ~(15)N and ~(29)Si NMR spectroscopy in solution, by ~(13)C, ~(15)N and ~(29)Si MAS NMR spectroscopy in the solid state, as well as by single-crystal and powder X-ray diffraction. The title compound exists as a single isomer in solution, whereas in the solid state the presence of several modifications is indicated, in particular by the solid-state MAS NMR spectra.
