“…[144][145][146][147][148] Research efforts towards developing viable and environmentally benign synthetic methodologies for oxidation of organic sulfides to sulfoxides and sulfones appear to have intensified, in recent times. [149][150][151] We could achieve clean conversion to high purity sulfoxide or sulfone from the corresponding sulfides as well as dibenzothiophene (DBT), in presence of catalytic amounts of the compounds MRVMo or MRAMo in impressive yields and TOF, by establishing appropriate reaction conditions.…”

Our recent achievements concerning the synthesis and characterization of water soluble peroxo complexes of V(V) and Mo(VI) in macroligand environment, as well as some key features of biological relevance of these compounds, such as their hydrolytic stability, activity with phosphohydrolase enzyme vis-à-vis free peroxovanadium (pV) or peroxomolybdenum (pMo) complexes, and their activity in biomimetic oxidative bromination are presented here. Immobilization of pMo species on insoluble polymer matrices viz., amino acid functionalized Merrifield resins and poly(acrylonitrile) on the other hand, afforded a set of heterogeneous catalysts highly effective in facile organic transformations such as selective oxidation of organic sulfides and oxidative bromination of aromatic substrates by H 2 O 2 , at ambient temperature. The methodologies are straightforward, high-yielding, halogen-free and the catalysts afford easy regeneration. Our findings illustrate the various features which make the procedures sustainable and synthetically useful.

“…In particular, the catalysis of alkene oxidation by soluble transition metal complexes is of great interest in both biomimetic chemistry and synthetic chemistry [6]. So far various Schiff base complexes have been employed to catalytic oxidation of olefins to epoxides and aldehydes, and it has been proved that many Schiff base complexes gave improved results as catalysts for these kinds of oxidation reactions [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In our research, the synthesized Schiff base complexes have been searched for their potential use as catalysts in oxidation reactions for both cyclohexene and styrene.…”

Carbazoles containing two new Schiff bases (Z,Z)-N,N -bis[(9-ethyl-9H-carbazole-and their Co(II) and Mn(II) complexes were synthesized and characterized using various spectroscopic methods and thermal analysis, which gave high thermal stability results for the ligands and their cobalt complexes. The title compounds were examined for their antimicrobial and antifungal activities, which resulted in high activity values for the ligands and their manganese complexes. Oxidation reactions carried out on styrene and cyclohexene revealed that the complex compounds were the most effective catalysts for styrene oxidation, giving good selectivities than those of cyclohexene oxidation. Electronic features of the synthesized compounds were also reported within this work.

“…Romanowskiron and Kira have reported the preparation a series of vanadium(V) complexes with chiral tridentate Schiff base ligands, obtained by the single condensation of R ‐(−)‐phenylglycinol with salicylaldehyde and its derivatives. The vanadium(V) complexes have the ability to catalyze the oxidation of sulfides (PhSR; R = Me, Bz) in excellent yields and enantiomeric excesses (over 90%) significantly depending on the nature of the catalyst, utilizing aqueous 30% H 2 O 2 or α,α‐dimethylbenzyl hydroperoxide as the oxidant (Figure ).…”

Schiff bases and their complexes are good candidates as versatile compounds which are synthesized by the condensation of a primary amino compound with either aldehydes or ketones for a variety of industrial applications. They can act as catalysts in the catalytic oxidation of organic compounds. Recent researches in oxidation catalysis have focused on how to employ the metal‐catalyzed oxidation of organic substrates. This review summarizes the current developments of the last few decades for the oxidations of organic compounds that proceed through Schiff base complexes. The chemical syntheses of Schiff bases and their complexes are outlined.
