A catalytic system made of a copper salt, potassium carbonate and PEG 3400 was developed to perform a Heck arylation under microwave activation. Copper iodide gave the best results in a short reaction time (30 min) and various substituted tert-butyl cinnamates could be synthesized. Better results were usually obtained after recycling the catalyst/solvent system.
开发了一种由
铜盐、
碳酸钾和P
EG 3400组成的催化系统,以在微波激活下进行Heck芳基化反应。
碘化
铜在短反应时间(30分钟)内表现出最佳效果,并且可以合成多种取代的叔丁基
肉桂酸酯。通常在回收催化剂/溶剂系统后可以获得更好的结果。
