Abstract

The reactions between equimolecular amounts of 4-bromophenylboronic acid and di-tertbutylsilanediol 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)₄O ₁₀] (2), in medium (62%) and low (13%) yields, respectively. These compounds were characterised by microanalysis, IR and NMR (¹H, ¹¹B, ¹³C and ²⁹Si) 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.
