with readily prepared cobalt or titanium nanoparticles, under mild reaction conditions, led to the obtention of different reductive dimerization products depending on the nature of the transition metal used. Cobalt nanoparticles (CoNPs) allowed the selective transformation of the starting carbonyl compounds into vicinal diols, whereas the reaction promoted by titanium nanoparticles (TiNPs) led to the
一系列醛和酮与容易制备的钴或钛纳米粒子在温和的反应条件下反应,导致根据所用过渡金属的性质获得不同的还原二聚产物。钴纳米粒子 (CoNPs) 允许将起始羰基化合物选择性转化为邻二醇,而钛纳米粒子 (TiNPs) 促进的反应导致相应烯烃的形成。在最后一种情况下,在 0 oC 下使用三甲基氯硅烷 (TMSCl) 作为添加剂也可以在酸性水溶液处理后获得邻二醇。
