using a phosphetane oxide catalyst in the presence of a simple organosilane as the terminal reductant and water as the hydrogen source. Quantitative hydrogenation was observed when 1.0 mol % of a methyl‐substituted phosphetane oxide was employed as the catalyst. The procedure is highly selective towards activated double bonds, tolerating a variety of functional groups that are usually prone to reduction
在简单的有机
硅烷作为末端还原剂和
水作为氢源的情况下,使用氧化膦催化剂可以轻松地还原不饱和羰基化合物的碳-碳双键。当使用1.0 mol%的甲基取代的氧化膦作为催化剂时,可以观察到定量氢化。该方法对活化的双键具有高度选择性,可以耐受通常易于还原的各种官能团。总共将25个烯烃和两个
炔烃氢化成相应的
烷烃,产率高达99%。值得注意的是,活性较低的聚(甲基氢
硅氧烷)也可以用作末端还原剂。
