prepared using Schiff's bases derived from aromatic aldehydes and amines or α-aminoesters. These complexes are versatile catalyst for the reaction between aliphatic aldehydes and various alkenes. The outcome of the reaction is controlled by the electronic nature of the alkene as the electron deficient alkenes undergo oxidative addition of aldehydes followed by dioxygen incorporation to yield 2-hydr
可以使用衍生自芳族醛和胺或α-氨基酯的席夫碱制备各种钴(II)配合物。这些络合物是脂肪族醛与各种烯烃之间反应的通用催化剂。反应的结果受烯烃的电子性质控制,因为缺电子的烯烃经历醛的氧化加成反应,然后引入双氧生成2-羟基(酰氧基)-4-氧酸酯或腈,而未活化或富电子的烯烃则提供了相应的环氧化物。这些反应是通过自由基途径进行的,并提出了一种常见的酰基钴中间体,用于形成4和环氧化物7。
