摘要

我们开发了一种以 B2(OH)4 为还原剂，以两性树脂分散的钯纳米粒子为催化剂体系，在水介质中进行醛酮转移加氢反应的方法，其中水也可作为氢供体。包括脂肪族羰基化合物在内的多种醛和酮发生反应，分别生成相应的伯醇和仲醇。催化剂通过过滤回收，并重复使用了九次，其催化活性没有明显下降。

Transfer-Hydrogenation of Aldehydes and Ketones with Tetrahydroxydiboran in Water

We have developed a transfer hydrogenation of aldehydes and ketones with B2(OH)4 as a reductant and amphiphilic resin-dispersed palladium nanoparticles as a catalyst system in an aqueous medium, where water also serves as a hydrogen donor. A variety of aldehydes and ketones, including aliphatic carbonyl compounds, reacted to give the corresponding primary and secondary alcohols, respectively. The catalyst was recovered by filtration and reused nine times without a significant loss of its catalytic activity.
