摘要
比较了Heck反应中传统的催化剂在分离和回收方面的问题,介绍了负载型钯催化剂的优点,归纳了负载型钯催化剂按固相载体高分子、二氧化硅、活性炭、分子筛和金属氧化物等进行的分类,总结了各类负载型钯催化剂在Heck反应中的应用。认为目前还必须克服负载型催化剂易流失、成本高等问题。
The separation and recycling problems of traditional catalysts in Heck reaction were compared and the advantages of supported palladium catalysts were introduced. The classification of supported palladium catalyst based on the different solid carrier,such as high polymer, silica, active carbon, molecular sieve and metal oxides were concluded, summarized the applications of all kinds of supported palladium catalyst in Heck reactions. We must overcome the problems of the easy loss supported catalyst and high cost.
