A green and highlyefficient protocol has been developed for the synthesis of phenyldiazenyl-acridinedione-carboxylic acids by a one-pot multicomponent coupling of 1,3-dicarbonyl compounds, 4-hydroxy-3-methoxy-5-(substituted-phenyl-diazenyl)-benzaldehydes and glycine using europium modified ceria nanoparticles as the catalyst in aqueous medium. An environmentallybenign reaction procedure, a wide diversity
