(Poly)glycerol monoethers were synthesized in good yield and selectivity by the catalytic reductive alkylation of glycerol, diglycerol, and triglycerol with readily available, cheap and/or bio‐sourced carboxylic acids. The reaction was catalyzed by 1 mol % of Pd/C under 50 bar H2 using an acid ion‐exchange resin as a recyclable cocatalyst. The catalytic system was recycled several times, and a mechanism
(聚)甘油单醚是通过甘油,二甘油和三甘油与现成的廉价和/或生物来源的羧酸的催化还原烷基化反应而合成的,具有良好的收率和选择性。使用酸性离子交换树脂作为可循环助催化剂,在50 bar H 2下以1 mol%的Pd / C催化反应。催化系统被回收了几次,并提出了这种转化的机理。
