protocol for reducing imines to amines. Thus, treatment of any of a wide array of imines with catalytic n-butyltris(2-ethylhexanoate)tin and stoichioimetric polymethylhydrosiloxane (PMHS) in ethanol at room temperature cleanly affords the desired secondary amine product. Alkyl bromides, alkynes, epoxides, esters, nitriles, and olefins are inert toward these reduction conditions, whereas aldehydes, ketones
我们已经开发出一种温和,方便且廉价的方案,用于将亚胺还原为胺。因此,在室温下用乙醇中的催化正丁基三(2-乙基己酸酯)锡和化学计量的聚甲基氢硅氧烷(PMHS)处理各种各样的亚胺,可以干净地得到所需的仲胺产物。烷基溴化物,炔烃,环氧化物,酯,腈和烯烃对这些还原条件呈惰性,而醛,酮和硝基化合物则不呈惰性。
