摘要

The reaction of a metastable SiCl2 solution with the sterically less-demanding carbene N, N-diisopropylimidazo- 2-ylidene (IPr) yields the salt [(IPr3Si3Cl5)(+)] Cl- (1-Cl), containing a silyl cation with a Si-3 backbone. Salt 1 is highly reactive, but it can be used as a reagent in deuterated dichloromethane, whereby dehalogenation with Me3SiOTf (OTf = O3SCF3) gives the dicationic silyl halide [(IPr3Si3Cl4)](2+) 2. Quantum chemical calculations show that the HOMO is localized at the negatively charged central silicon atom of 1 and 2, and thus although both compounds are cations they are better described as silanides, which was also corroborated by NMR investigations.
