| Abstract | ||
| The synthesized ternary metal complex was immobilized onto ammonium salt of phosphotungstate (NH4)3(PW12O40) under solvothermal condition to synthesize a new organic-inorganic hybrid (NH4)3[(CuComplex)(PW12O40)]. The synthesized metal complex and the hybrid (NH4)3[(CuComplex)(PW12O40)] were characterized by FT-IR, CHNO elemental analysis, SEM, powder-XRD, DR UV-Vis. Hybrid was further characterized by EDX. The metal complex as well as organic-inorganic hybrid were studied for their catalytic activity in oxidative conversion of alkyl aromatic, cycloalkane and cycloalcohols. The products formed during catalysis were analyzed by gas chromatography (GC) –mass spectroscopy (MS). The heterogeneous catalyst was recycled and reused multiple times with no substantial loss of their catalytic activity. A green procedure was followed and no toxic chemicals were released during solvothermal synthesis of heterogeneous catalyst. The resulting catalytic oxidation products are valuable intermediates and are employed for various medicinal and pharmaceutical industrial synthesis. | ||
