Abstract

This study presents the synthesis of organoboron derivatives of stereoregular 4-, 6-, and 12-unit phenylcyclosilsesquioxanes. All compounds obtained were isolated in good yields (70-80 %) and were fully characterized by ¹ H, ¹³ C, ²⁹ Si, ¹¹ B NMR, IR spectroscopy, HRMS ESI, and elemental microanalysis. The structure of the key modifier, obtained for the first time, 4-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl) dimethylvinylsilane, was also confirmed by single-crystal XRD.

Keywords: coordination chemistry; inorganic chemistry; methodology and reactions; organoboron derivatives; organocyclosilsesquioxanes.
