Abstract

A three-component reaction of aryl bromides, potassium cyanate, and secondary amines takes place at 110° C in MeCN under the catalysis of Cu2O and 2-(2, 6- dimethylphenylamino)-2-oxoacetic acid potassium salt, giving N, N-disubstituted-N′- arylureas in good to excellent yields. A number of functionalized aryl bromides and secondary amines were compatible with these conditions, and thereby providing a facile ...
