Polymer-bound DBU (PS-DBU, DBU = 1,8-diazabicyclo[5.4.0]undec-7-ene) is an effective and selective catalyst for solventless N-phenoxycarbonylation of N-heteroaromatics (pyrrole (1), indole (2), and carbazole (3)) with diphenyl carbonate (DPC), used as an

A new simple approach to the synthesis of unsymmetrical ureas HetNC(O)NRR′ (HetNH = pyrrole, indole, carbazole; R, R′ = H, alkyl, aryl) has been explored, which involves the direct reaction of the N-phenoxycarbonyl derivatives of pyrrole, indole and carba
