Schiff base Mn(iii) and Co(ii) complexes coated on Co nanoparticles: an efficient and recyclable magnetic nanocatalyst for H₂O₂ oxidation of sulfides to sulfoxides

Abstract

In this paper, an effective and selective heterogeneous catalyst was produced by immobilization of manganese and cobalt Schiff base-complexes on Co magnetite nanoparticles (MNP).

Selective Photooxidation of Amines and Sulfides Triggered by a Superoxide Radical Using a Novel Visible-Light-Responsive Metal–Organic Framework

“…Beyond molecular oxygen, hydrogen peroxide (H 2 O 2 ) has been demonstrated to be an effective oxidant for the catalytic oxygenation of sulfides and it is a benign chemical to the environment. − However, to the best of our knowledge, the use of it in the photocatalytic system of MOFs for the oxidation of sulfides has not been investigated so far. After removal of molecular oxygen by three freeze–pump–thaw cycles, the oxidation of sulfide by H 2 O 2 was first investigated under N 2 atmosphere.…”

Nanomagnetic macrocyclic Schiff-base–Mn(ii) complex: an efficient heterogeneous catalyst for click approach synthesis of novel β-substitued-1,2,3-triazoles

“…[72][73][74] Nanoparticles based on Schiff's bases-metal complexes are important classes of hetrogenized organic ligands and complexes and important parts of green chemistry, they constitute the largest and the most diverse family of organic ligands with chemical, biomedical and industrial signicance. [75][76][77] In these complexes, both of the nitrogen and carbon centers are coordinate to metal ions via electron donation from C]N p and s* orbitals into the empty orbital of transition metals and electron donation from the transition metal d orbital into the C]N p* orbital (p-back bonding) respectively. [78][79][80] These compounds are privileged in the structure of many transition metal complexes, catalysts, drugs and biological and pharmaceutical molecules.…”
