转移氢化反应是一种条件温和、反应转化率高的还原反应.研究了一系列双烷基和双羟基修饰的炔类化合物,在空气中水合肼的作用下选择性还原为顺式烯烃的方法,其中水合肼作为转移氢化试剂,空气中氧气作为氧化剂,通过氧化反应将肼氧化为二氮烯N2H2分子,进而二氮烯N2H2分子选择性还原炔烃为顺式烯烃.通过二维核磁共振谱证明了生成的烯烃的构型为顺式结构.

关键词: 转移氢化, 水合肼, 炔烃, 烯烃, 二氮烯

Transfer hydrogenation is a mild and effective way in reduction reaction. In this paper, a simple approach of selectively hydrogenation of alkynes to cis-alkenes with NH2NH2·H2O as a transfer hydrogenation agent in the presence of air without any catalysts or metals was developed. Furthermore, the configuration of cis-alkene was confirmed by the 2D NOESY spectrum.

Key words: transfer hydrogenation, hydrazine, alkynes, alkenes, diazene
