Chemoselective semihydrogenation of alkynes to alkenes with E- or Z-stereoselectivity is among the most important transformations in the synthesis of highly functional organic building blocks. Use of hydrogen transfer reagents instead of gaseous hydrogen represents a viable, safe alternative in many cases. This review summarises recent developments in the field using homogeneous, molecularly defined catalyst systems with focus on hydrogen sources and mechanistic aspects of the respective systems.

炔烃的均相催化转移半氢化反应–氢源，催化剂和反应机理的概述

炔的化学选择性半氢化为具有E-或Z-立体选择性的烯烃是合成高功能有机结构单元中最重要的转变之一。在许多情况下，使用氢转移试剂代替气态氢是一种可行，安全的选择。这篇综述总结了使用均相的，分子限定的催化剂体系在该领域的最新进展，重点是氢源和各个体系的机械方面。
