Abstract

A carborane-fused silylene 1-{[PhC(NtBu)₂]Si}-1,2-C₂B₁₀H₁₁ (2) has been prepared and structurally characterized from an equimolar reaction of 1-Li-1,2-C₂B₁₀H₁₁ with [PhC(N^tBu)₂]SiCl (1) in Et₂O. The reactions of 2 with elemental sulfur and benzophenone afforded the corresponding o-carborane substituted silanethione (3) and silaoxirane (4), respectively. On the other hand, the reaction of 2 with 2-benzoylpyridine led to the isolation of an unexpected compound 5 featuring a SiC₂O₂ five-membered ring. All new compounds were characterized by multiple NMR spectroscopic techniques and single-crystal X-ray analyses.
