描述
应用 |
A promoter of O-alkylation of alcohols.提高醇 O-烷基化的效率以生成碳酸烷基酯混合物。 Cesium carbonate is an attractive base that finds more and more applications in coupling chemistry. Cesium carbonate has been employed as catalyst for: · Aerobic oxidation of primary alcohols. · 1,4-addition. Cesium carbonate has been used as reagent for the following studies: · Synthesis of phosphazene derivatives. · Constrictive binding interactions. · Intramolecular C-N cross coupling reactions. · Dehydohalogenative polycondensation. |
产品介绍 | Cesium carbonate promotes the efficient O-alkylation of alcohols to form mixed alkyl carbonates. It is a catalyst for aerobic oxidation of primary alcohols, 1,4-addition reactions, intramolecular C-N cross coupling reactions and dehydrohalogenative polycondensation reactions. |
