Reaction Conditions:
with sulfuric acid in neat (no solvent);Microwave irradiation;Sealed tube;Green chemistry;
Steps:
synthesis of imines
General procedure: An appropriate equi-molar quantities of aryl amines (2 mmol), substituted benzaldehydes (2 mmol) and fly-ash: H2SO4 (0.5 g) have been taken in ACE tube and tightly capped. The mixture has been subjected to microwave irradiation for 6-12 min in a microwave oven (Scheme 1) (LG Grill, Intellowave, Microwave Oven, 160-800 W) and then cooled to room temperature. After separating the organic layer with dichloromethane the solid product has been obtained on evaporation. The solid, on recrystallization from benzene-hexane mixture afforded glittering product. The insoluble catalyst has been recycled by washing with ethyl acetate (8 mL) followed by drying in an oven at 100 °C for 1 h and reused for further reactions.
