WebDiborane can be generated by the reaction of BF 3 •OEt 2 with LiH 8 or by the reaction of NaBH 4 and BF 3 (see Section 9.1). 9 Borane is a good Lewis acid and coordinates to atoms of high-electron density (e.g., Lewis bases). Borane coordinates with Lewis bases, which influences the reducing power of borane.
