微波配体共同促进的二芳基丙烯酸类化合物的脱羧反应

摘要

研究了在微波和配体共同作用下,数种2,3-二芳基丙烯酸类化合物的脱羧反应。在铜粉/喹啉体系中及催化量的邻菲咯啉存在时,2,3-二芳基丙烯酸类化合物在微波辐照下,数分钟内即可完成脱酸反应,高收率地得到二苯乙烯类化合物。%Decarboxylation of several 2,3-diaryl acrylic acids has been investigated.2,3-Diaryl acrylic acids can be efficiently decarboxylated in the presence of copper powder,quinoline,and catalytic amount of 1,10-phenanthroline under microwave conditions in a few minutes,affording the corresponding stilbenes in high yields.
