摘要：

The reactions between equimolecular amounts of 4-bromophenylboronic acid and di-tert-butylsilanediol or tert-butylsilanetriol in toluene solutions at reflux temperatures afforded the borosilicate ring compound [(4-BrC6H4B) O2Si(t-Bu)(2)](2) (1), and the cube-based species [(t-BuSi)(4) (4-BrC6H4B)(4)O-10](2), in medium (62%) and low (13%) yields, respectively. These compounds were characterised by microanalysis, IR and NMR (H-1, B-11, C-13 and Si-29) spectroscopy and single crystal X-ray crystallography. During the work-up of 2, a sample of the boroxine, [(4-BrC6H4BO)(3)](3), was isolated and was characterised by single crystal diffraction.
