文摘

The dehydrohalogenation of a silicon(IV)-substituted diphenyl hydrazone derivative leads to a dimer of a N-substituted hydrosila hydrazone, which consists of a four-membered Si₂N₂ core and a hydrogen attached to each of the silicon atoms instead of giving a substituted hydrosilaneimine. The compound is obviously formed by dimerization of hydrosilaneimine. Moreover there are no straightforward synthetic methods known for the synthesis of silaaziridine. The preparation of such species would be of special importance for the development of a new field of silicon chemistry. The reaction of chlorosilylene, LSiCl, and PhCH鈺怤Ph resulted in a base-stabilized silaaziridine. All compounds were characterized by NMR spectroscopy, mass spectrometry, microanalysis, and X-ray structural analysis.
