Carbon Dioxide-Mediated Preparation of Amine-BoranesDaniel O'Neal Reddy (8893829) 15 June 2020 (has links)
<p>Since their discovery by Burg and Schlesinger in 1937, amine-boranes have enjoyed a rich preparative history and have experienced reinvigorated interest as valuable reagents for organic syntheses. Previously, the Herbert C. Brown Center for Borane Research has reported their synthesis from NaBH<sub>4</sub> and amines via the intermediacy of (NH<sub>4</sub>)<sub>2</sub>SO4 or NaHCO<sub>3</sub>. Described herein is a CO<sub>2</sub>-mediated amine-borane synthesis that accommodates all classes of amines, particularly long-chain trialkyl- and pyridine-like heteroarylamines.</p>
