本文介绍了应用日益广泛并具有优良理化性能的硼系还原剂之一——异丙胺甲硼烷的合成方法。这是一种方法简便、收率较高的一步合成法。测定产物的熔点和IR.NMR谱图,证实合成产物为异丙胺甲硼烷。 This paper introduces the synthesis of isopropylamine borane, one of the boron-based reducing agents, which is widely used and has excellent physical and chemical properties. This is a simple, high yield one-step synthesis method. The melting point and IR.NMR spectra of the product were determined to confirm that the product of synthesis was isopropylamine borane.
