The reaction of heteroleptic silylene LSiNPh<sub>2</sub> [L = PhC(N<i>t</i>Bu)<sub>2</sub>] with diazobenzene afforded
product <b>6</b>. This involves one <i>o</i>-C–H
bond activation
at one of the phenyl groups of diazobenzene and migration of this
hydrogen atom from the phenyl ring to one of the nitrogen atoms, which
leads to the formation of the new C–Si and N–Si bonds.
The reaction of benzylidineaniline with LSiNPh<sub>2</sub> results
in the oxidative addition of the three-membered silaaziridine derivative <b>7</b>. Compounds <b>6</b> and <b>7</b> were fully
characterized by elemental analysis, multinuclear NMR spectroscopy,
and EI-MS spectrometry. The molecular structures of compounds <b>6</b> and <b>7</b> were established unequivocally by single-crystal
X-ray structural analysis
