Synthesis of 2-methoxy-4,4,5,5-tetramethyl[1,3,2]dioxaborolane
Synthesis of 2-methoxy-4,4,5,5-tetramethyl[1,3,2]dioxaborolane A flask equipped with a reflux condenser, stirrer, an inert gas inlet and a thermocouple set in heating mantle was charged with trimethyl borate and pinacol under positive pressure of nitrogen. The resulting mixture was heated at reflux for 6 hours. The mixture was cooled to ambient temperatures and transferred to a flask with a Vigreux column. The mixture was distilled at atmospheric pressure to afford 2-methoxy-4,4,5,5-tetramethyl[1,3,2]dioxaborolane (bp 159° C.) in high yield (90%). 1H NMR (400 MHz, CDCl3): δ 3.41 (m, 3H), 1.11 (m, 12H). 11B NMR (128.3 MHz, CDCl3): δ 22.2. 13C NMR (100.6 MHz, CDCl3): δ 82.7, 52.6, 24.6.
