A facile and high-yielding one-pot synthesis of carbamates and N, N'-disubstituted symmetrical ureas from N-acylbenzotriazoles has been devised. It is believed that, the intermediate acyl-azide undergo Curtius rearrangement and in different solvents gives different products i.e. carbamates in alcohols and N, N'-disubstituted symmetrical urea in THF.
