GRAPHICAL ABSTRACT

ABSTRACT

A facile and useful method for synthesis of 1-benzylidene semicarbazones was introduced in this work. The reaction of synthesis of the corresponding 1-benzylidene semicarbazone derivatives is carried out in the presence of acetonitrile-UHP/NH4OAc. In this method, NH4OAc was used as a source of ammonia and urea-hydrogen peroxide (UHP) as reagent. The key advantages of this process are elimination of semicarbazide, good yields and cheap reagents. All products were characterized by common techniques (infrared, 1H NMR, and melting point).
