A review is provided of the recent progress in catalytic hydrogenation of C=C bond.The catalytic hydrogenation with molecular hydrogen and catalytic transfer hydrogenation without molecular hydrogen are summarized. It is pointed out that catalytic transfer hydrogenation including photo transfer hydrogenation has the advantages such as mild reaction condition and high safety, showing promising potential in industrial hydrogenation of C=C bond.%综述了近年来碳碳双键催化加氢的研究进展;分别针对以氢气为氢源的催化加氢反应和以非氢气为氢源的催化转移加氢反应进行了分析概括;指出其中催化转移加氢(包括光照下转移加氢)具有反应条件温和且操作安全简便的优势,应用前景广阔.
