A rapid, highly efficient and mild greensynthesis of 5,5‐diphenylhydantoin derivatives was achieved from the reaction of symmetrical or unsymmetricalbenzilderivatives with urea in the presence of ethanolic KOH under ultrasound irradiation. This simple method affords 5,5‐diphenylhydantoin derivatives at room temperature in short reaction time with high yield and purity. This study aimed to overcome
