  • Abstract

    A green and facile synthesis of N,N'-disubstituted urea from biuret and different amines have been developed using ZrOCl2.8H2O as catalyst in the absence of solvent under microwave irradiations. The remarkable features of this protocol are higher yield in shorter reaction time, use of non-toxic and readily available catalyst, clement and environment affable reaction conditions and simple work up procedures
