摘要

The reactivity of recently introduced N-heterocyclic silylene [PhC(NtBu)(2)](C5Me5)Si was evaluated. Three different reaction pathways were studied: (1) coordination to a Lewis acid, (2) oxidation by chalcogenides, and (3) coordination to transition metal complexes. The reaction of the silylene with BH3 led to the adduct [PhC(NtBu)(2)](C5Me5)Si(BH)(3). Oxidation with the elemental chalcogens sulphur, selenium, and tellurium resulted in the corresponding silicon(IV)-chalcogenide compounds [PhC(NtBu)(2)](C5Me5)SiS, [PhC (NtBu)(2)](C5Me5)SiSe and [PhC(NtBu)(2)](C5Me5)SiTe. Treatment of the silylene with dimeric group 9 transition metal complexes [Ir(COD)Cl](2) and [Rh(COD)Cl](2) gave square planar coordinated transition metal silylene complexes [{PhC(NtBu)(2)}(C5Me5)Si-Rh(COD)(Cl)] and [{PhC(NtBu)(2)}(C5Me5)Si-Ir(COD)(Cl)].
