研究了多官能生物碱辛可宁、辛可尼定和奎宁与Ｈ３Ｂ·Ｓ（ＣＨ３）２的反应；其产物组成和结构与反应物配比有关．在实验条件下，生物碱与Ｈ３Ｂ·Ｓ（ＣＨ３）２等摩尔反应生成单甲硼烷配合物；在Ｈ３Ｂ·Ｓ（ＣＨ３）２过量时，最多只能得到含两个硼原子的化合物，生物碱分子中的烯键对Ｈ３Ｂ·Ｓ（ＣＨ３）２表现出惰性．
The reaction of multifunctional alkaloids such as cinchonine, cinchonidine and quinine with H3B · S (CH3) 2 was studied. The composition and structure of the products were related to the ratio of reactants. Under the experimental conditions, alkaloids react with equimolar H3B · S (CH3) 2 to form monoborane complexes. When H3B · S (CH3) 2 is in excess, only up to two compounds containing two boron atoms can be obtained. The olefinic bond in the base molecule appears to be inert to H3B.S (CH3) 2.
