The reaction of bis[bis(trimethylsilyl)methyl] germylene (1) with 1,1-
diazidosilanes gave siladihydrotetrazole derivative and cyclodisilazan
e. The structure of the latter has been confirmed by single-crystal X-
ray diffraction. The similar reaction of I or bis[bis(trimethylsilyl)m
ethyl]stannylene with 1,3-diazidohexamethyltrisilane furnished azatris
ilacyclobutanes in quantitative yield respectively.
