“…Numerous reagents and methods are reported for these conversions [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47], but development of environmentally benign processes are a challenge. Cu(II) complexes are useful metal mediated catalysts in these conversions.…”

Ni(II), Cu(II), Co(II) and Pd(II) complexes were synthesized with a Schiff base containing thioether with ONS-donors chelating to the metal center. The ligand and complexes were characterized by elemental analysis, FT-IR, 1 H-NMR, UV-visible spectroscopy and magnetic studies. The crystal structures of the ligand and its Ni(II) and Pd(II) complexes were determined by single-crystal X-ray diffraction analysis. The structure reveals that ligand-chelated Ni(II) andPd(II) in slightly distorted octahedral and slightly distorted square planar environment, respectively. DFT studies of the Pd(II) complex reveal that the calculated structural parameters are very close with the experimentally observed data. The Cu(II) complex shows very good catalytic activity towards conversion of alcohol to aldehyde under aerobic oxidation with ammonium persulfate.

“…It acquires properties like high surface area, tunable pore size and functionality, crystalline open structures, high adsorption capacity, and partitioning of reactant/products, which allows considering them as potential supports for entrapment of catalytically active complexes or metal complexes . These inorganic‐crossbred porous framework compounds not only possess heterogeneous catalytic physiognomies, but also conserve high catalytic efficacy originating in homogeneous catalysis due to the site sheltered effect …”

Transition metal [M = VO (IV) and/or Cu (II)] complexes with Schiff base ligand, (Z)-2-((2-hydroxybenzylideneamino)phenol (H 2 L) have been entrapped in the super cages of zeolite-Y by Flexible Ligand Method. Synthesized materials have been characterized by preferential physico-chemical techniques such as inductively coupled plasma optical emission spectroscopy (ICP-OES), elemental analyses (CHN), fourier transmission infrared spectroscopy (FTIR), electronic and UVreflectance spectra, Brunauer-Emmett-Teller (BET) surface area measurements, scanning electron micrographs (SEMs), X-ray diffraction patterns (XRD) and thermogravimetric analysis (TGA). The catalytic competence of zeolite-Y entrapped transition metal complexes was examined in Baeyer-Villiger (BV) oxidation of cyclopentanone using 30% H 2 O 2 as an oxidant beside neat complexes to check the aptitude of heterogeneous catalysis over the homogeneous system. The effect of experimental variables such as mole ratio of substrate to an oxidant, amount of catalyst, reaction time, varying oxidants and solvents on the conversion of cyclopentanone was also tested. Under the optimized reaction conditions, one of the zeolite-Y entrapped transition metal complex viz. [VO(L)H 2 O]-Y [where L = (Z)-2-((2-hydroxybenzylideneamino)phenol] was found to be a potential contender by providing 80.22% conversion of cyclopentanone (TON: 10479.42), and the selectivity towards δ-valerolactone was 83.56%.
