    • Abstract


      The rapid and highly efficient synthesis of 5,5-disubstituted hydantoins achieved by threecomponent condensation of corresponding ketones and aldehydes, potassium cyanide and ammonium carbonate in an additional reaction under ultrasound irradiation by using montmorillonite K-10 as a heterogenous catalyst. Utilizing ultrasound irradiation and montmorillonite in this method has several benefits, for example short reaction time, high yield and use of recyclable catalyst.
