摘要

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 center dot 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.
