铯盐如Cs2CO3, CsF等因在钯催化碳碳偶联, N, O, S的烃基化反应中表现出良好的性能而引起了人们的广泛关注. 介绍了铯盐在钯催化的Suzuki, Heck, Stille, Sonogashira反应, 烯醇盐的芳基化, 酚类的邻位芳基化以及羰基化反应中的促进作用. 同时还对铯盐参与的N, O, S等的烃基化反应进行了讨论, 并侧重于与其他碱金属盐的对比.

关键词: 铯盐, Suzuki反应, Heck反应, Stille反应, Sonogashira反应, 烷基化, 芳基化

Cesium salts such as Cs2CO3, CsF, etc. have attracted much attention for their good effect on promoting Pd-catalyzed C—C formation coupling, alkylation and arylation of N, O and S atoms. This paper introduces the salt assistance to Pd-catalyzed Suzuki, Heck, Stille and Sonogashira reactions as well as arylation of enolate, ortho-arylation of phenol and carbonylation. The Cs-mediated alkylation and arylation of N, O and S atoms are also discussed, with emphases placed upon the comparison of cesium salts with their potassium or sodium analogs.

Key words: alkylation, Suzuki reaction, Sonogashira reaction, arylation, Heck reaction, Stille reaction, cesium salt
