Thermally Stable Four-Coordinate Silicon(IV) Complexes with an Si=N Double Bond and an SiN(3)El Skeleton (El = O, S, Se, Te)

摘要

The donor-stabilized silylene 1 reacts with N2O and PhElElPh (El = S, Se, Te) to form the respective silicon(IV) complexes 2-5 with an Si=N double bond. Compounds 2-5 were structurally characterized by crystal structure analyses and NMR spectroscopic studies in the solid state and in solution.
