  • Published:1997-10-25

羰基化合物还原偶合是形成碳-碳键的一种重要方法。本文首次发现此类反应的产物不仅与反应物本身的结构和还原试剂体系有关,还与操作次序有很大关系,且在活性钛表面反应。

The reductive coupling of carbonyl compounds constitutes an important method for the formation of carbon-carbon bonds. In present paper, we have found for the first time that the products of the carbonyl coupling reaction not only depend on reactants and reagent systems, but also operation sequence. It is believed that the coupling reaction occurs on the surface of the active titanium particle.
