2-Amino-5,10-dioxo-4-aryl-5,10-dihydro-4H-benzo[g]chromene-3-carbonitrile derivatives are obtained in excellent yields with a simple and efficient procedure.This reaction can occur using electrocatalytic multicomponent chain transformation of aryl aldehydes, 2-hydroxynaphthalene-1,4-dione and malononitrile under neutral and mild conditions. Moreover, electrolysis is done in CH3CN as solvent, Tetrabutylammonium fluoride (TBAF) as an effective supporting electrolyte and an iron electrode as the cathode and a graphite electrode as the anode in undivided cell. Also Excellent conversions of the starting materials were obtained under 10 mA/cm2 current densities after 0.54 F/mol of electricity had been passed and I=50 mA at room temperature. The key advantages of this method are the high yields, simple work up the non-chromatographic purification of products.

An efficient synthetic method for successful synthesis of amine denderon on SBA-15 and related Pd (II) complex has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N2 adsorption-desorption, and FT-IR. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of alcohols as model reactions. The yields of the products were in the range from 75% to 92%. The catalyst can be readily recovered and reused at least 5 consecutive cycles without significant leaching and loss its catalytic activity.
