一般說明

碳酸铯是一种强无机碱，广泛用于有机合成。它是一种潜在的化学选择性催化剂，将醛和酮还原成醇。在4-三氟甲基-1-氯苯和芳基氯化物的Heck偶联反应中，它可用作碱。

應用

提高醇 O-烷基化的效率以生成碳酸烷基酯混合物。
碳酸铯可在C-C和C-N交叉偶联反应用作中底物，如Suzuki−Miyaura、Heck和Buchwald-Hartwig胺化反应。它还可在烷基化反应中用作底物。

Cs2CO3 has been found to be an efficient and chemoselective catalyst for reduction of aldehydes and ketones to alcohols with one equivalent of Ph2SiH2 as the reductant under solvent-free conditions. Most of the aldehydes employed can be effectively hydrosilated quantitatively

A detailed investigation into the influence of phosphines, additives, bases and solvents on the Heck coupling reaction of 4-trifluoromethyl-1-chlorobenzene (2) is presented. It is shown that a number of catalyst systems exist for efficient cross coupling of electron-deficient aryl chlorides
