E-Selective semi-hydrogenation of alkynes via a sulfur-radical mediation over cyclodextrin-modified nickel nanocatalyst

Abstract

A nickel-based catalytic system, including simple NiCl2·6H2O, sodium borohydride and mercapto-β-cyclodextrin (CD-SH), is developed for the semi-hydrogenation of alkynes to E-alkenes. This system features a high efficiency with good E-selectivity...
