A rapid and efficient synthesis of 3,5-diaryl-2,6-dicyanoanilines has been developed via the reaction of arylidenemalonodinitriles with 1-arylethylidenemalonodinitriles in the presence of KF/ alumina as catalyst under microwave irradiation without solvent. Use of non-hazardous solid base as a catalyst, operational simplicity, short reaction times and excellent yields are the key advantages of the present protocol.
