摘要本文探究了金属纳米催化剂催化糖基三氮唑末端烯烃生成酮的方法,筛选出了该反应的最佳条件,并探究了该反应对各种末端烯烃的适应性。金属纳米催化剂是介于非均相催化剂和均相催化剂的另一种形态,且它的优点优于非均相催化剂和均相催化剂,具有高活性和高稳定性,易回收率等特点。同时利用该新型葡萄糖基衍生的吡啶三氮唑钯纳米催化剂催化氧化末端烯烃Wacker反应的方法能够实现相当高的产率,符合绿色化学的原则。该法为催化氧化末端烯烃提供了新的催化条件,具有重要意义。61356
Abstract: The method that the three azole nitrogen through the metal nanometer catalyst sugar-based catalytic olefin generated ketone was explored in this paper.The optimum reaction conditions are selected and the scope of the reaction was investigated. Metal nanometer catalyst is between heterogeneous catalyst and another form of homogeneous catalyst, and its advantages superior to and homogeneous catalyst and heterogeneous catalyst is highly active and high stability, easy recovery, etc. At the same time using the novel glucose derivative of pyridine three azole nitrogen nano palladium catalyst of catalytic oxidation terminal olefins Wacker method can achieve high yield, comply with the principles of green chemistry. The method for the catalytic oxidation terminal olefins provides new conditions, is of great significance.
