An effective protocol allows the smooth protodecarboxylation of diversely functionalized aromatic carboxylic acids within 5-15 min under microwave irradiation. In the presence of an inexpensive catalyst generated in situ from copper(I) oxide and 1,10-phenanthroline, even nonactivated benzoates were converted in high yields.
