Reduction
of (boryl)dibromosilane (boryl)SiHBr2 (1;
boryl = B(NArCH)2, Ar = 2,6-iPr2C6H3) with 2 equiv of potassium
graphite in DME at low temperature led to the isolation of bis(boryl)disilane
(boryl)SiH2SiH2(boryl) (3) as a
colorless solid, whereas reduction of (boryl)SiPhBr2 (2) in THF gave the boryl-substituted disilene (boryl)PhSiSiPh(boryl)
(4) as a yellow solid. The reaction of 1 with 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (IiPr) unexpectedly led to the formation of the cationic species [(boryl)SiHBr(IiPr)]+Br– (6).
These products were characterized by spectroscopic methods as well
as by X-ray single-crystal analysis.
