Baeyer-Villiger(BV)反应是有机化学合成中的一个重要反应.特别是催化型的BV反应不仅能够简化反应过程还能够降低反应物的消耗量和减少副产物的生成量,因此更加具有实际应用价值.其中最为有利的催化型BV反应是使用低成本、环境友好的过氧化氢(H_2O_2)作为氧化剂,来取代传统的氧化剂过酸.本综述首先简要阐述了以H_2O_2为氧化剂的BV氧化反应的特点以及传统使用的氧化剂类型,然后重点综述了Sn基催化剂材料在以H_2O_2为氧化剂的催化型BV反应中的催化性能以及相应的催化机理,具体包含了Sn基均相催化剂材料(例如Sn基含氟双相体系催化剂),Sn基异相催化剂材料(例如Sn基沸石,Sn基介孔复合物,Sn基粘土,Sn基金属氧化物,以及Sn基聚合物催化剂).最后,对以H_2O_2为氧化剂的BV反应的Sn基催化剂的实际应用进行了评论和展望,讨论了它们在提高BV氧化反应催化活性方面可能的改进和发展的方向.
Baeyer-Villiger (BV) reaction is an important reaction in organic chemical synthesis, especially the catalytic BV reaction can not only simplify the reaction process but also reduce the consumption of reactants and reduce the formation of by-products, so it is more practical The most promising catalytic BV reaction is the replacement of the conventional oxidant peracid by the use of low-cost, environmentally friendly hydrogen peroxide (H 2 O 2) as oxidant.This review first briefly described the effects of H 2 O 2 as oxidant on the oxidation of BV Characteristics and traditional types of oxidants, and then reviewed the catalytic performance of Sn-based catalyst materials in the catalytic BV reaction with H 2 O 2 as oxidant and the corresponding catalytic mechanism, including the Sn-based homogeneous catalyst materials (such as Sn-containing (Such as Sn-based zeolite, Sn-based mesoporous composite, Sn-based clay, Sn-based metal oxide and Sn-based polymer catalyst) .Finally, Comments on the practical application of Sn-based catalysts for the BV reaction of oxidants and their possible applications in improving the catalytic activity of BV oxidation reactions Into the direction and development.
