自1898年萨巴悌埃(Sabatier)、森德伦斯(Senderens)等人发现不饱和烃可以催化加氢以来,催化氢化已成为有机合成中重要的单元操作,这不仅在于它能对于一些含有碳-碳重键、羰基、硝基、氰基等化合物的加成或还原上~#,而且,催化氢化反应条件温和(可以在低温低压甚至常温常压下进行),几乎可以定量进行,并且不需要什么特殊溶剂。因此,催化氢化成为还原方法中的骄骄者。另外,某些对于高温、酸碱敏感的化合物,使用催化氢化可 Since 1898, Sabatier and Senderens et al. Found that unsaturated hydrocarbons can be catalytically hydrogenated, catalytic hydrogenation has become an important unit operation in organic synthesis not only because it can catalyze some of the Carbon-carbon multiple bonds, carbonyl, nitro, cyano and other compounds addition or reduction ~ #, and the catalytic hydrogenation reaction conditions (which can be at low temperature and low pressure even under normal temperature and pressure), almost quantitatively, and No special solvents required. Therefore, catalytic hydrogenation becomes the arrogant in the reduction method. In addition, some high temperature, acid-base compounds, the use of catalytic hydrogenation can be
