Abstract

The synthesis of a new Schiff base ligand “4-((Z)-((Z)-3-hydroxy-1,3-diphenylallylidene)amino) -1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one (APD)” and its palladium complex [Pd(APD)2] is described. The ligand and complex are characterized by FTIR, FESEM, EDX, Elemental analyses and Mass spectrometry. The structure of the ligand is also confirmed by single crystal X-ray determination and 1H NMR data. The complex is insoluble in almost all common organic solvents. It has been used as an efficient catalyst in a series of Heck-Mizoroki and Suzuki-Miyaura coupling reactions giving good TON and TOF. The ease of synthesis, air-stability and recyclability are some of the important characteristics of the synthesized catalyst.
