“…Another reason why the catalytic reactions of p(NaAMPS-co-AN)-[Mn(TMPyP] were lessened in the presence of H2O2 is that H2O2 was decomposed due to the existence of Mn ions in the reaction environment. [38,39]. Ultimately, owing to TBHP amphiphilic nature, TBHP facilitated the transmission of alcohols within the hydrophilic-Mn III active sites.…”

The present study aims to introduce a new catalytic system, namely poly[(2-acrylamido-2-methyl-1-propane sulfonic acid-co-acrylonitrile)-Mn(III) meso tetra(N-methyl-4-pyridyl) porphine briefly called p(NaAMPS-co-AN)‐[Mn(TMPyP)]. Free-radical polymerization at ambient temperature was employed to construct this catalytic system. To prepare this heterogeneous bi-phasic catalyst, poly(NaAMPS-co-AN) was axially grafted onto the metal centers of the MnIII composite. In order to identify the amounts of metals in prepared compound, atomic absorption spectroscopy (AAS) was utilized. The results indicated that p(NaAMPS-co-AN)‐[Mn(TMPyP)] had the potential to efficiently catalyze alcohol oxidation with high selectivity in the solid-liquid biphasic reaction system. Furthermore, the catalytic activities of alcohol oxidation by the reaction-controlled phase transfer catalyst system were compared in the presence of H2O2 and TBHP, as oxidants, in a biphasic environment. It was found that functioning as a nanoreactor, the prepared catalyst system facilitated the oxidation of alcohols in water, leading to the substantial acceleration of catalytic reaction rates. After the completion of the catalytic activity, the catalyst could be separated easily from the reaction media and reused without any activity loss. In effect, the quality of the catalyst remained the same for eight cycles. The excellent performance of p(NaAMPS-co-AN)‐[Mn(TMPyP] is mostly attributed to its macroporous structure which allow for a rapid diffusion of the reactants to the reactive Mn(III) centers. High stability and reusability of catalyst without leaching is may be due to the AN. In fact, p(NaAMPS-co-AN)‐[Mn(TMPyP)] has chemical cross-linker, MBA, and physical cross-linker, AN. In a similar vein, the FT-IR spectra and atomic absorption spectroscopy confirmed the great recyclability, durability, and leaching resistance of the catalyst.

Transition‐metal catalysts with phenolate ligands comprise a great variety of compounds with appropriate characteristics capable of promoting numerous reactions of extreme importance in synthetic organic chemistry. Included in these transformations are oxidations of alkenes, sulfides, alcohols, and alkanes, cyanations, alkynylations, alkylations, hydroaminations, and nitroaldol reactions. An extensive review of the catalysis of organic processes by metal phenolates has been presented in a previous volume of this series. This chapter is an update of the advances published from 2011 to the beginning of 2015, with emphasis on the type of reactions catalyzed by metal phenolates that have gained more attention in the literature during this period.

Tungstate ions were successfully loaded onto triazine-based ionic liquid-functionalized magnetic nanoparticles through an anion exchange process. The use of triazine core for creating ionic liquid led to the immobilization of high amounts of WO 4 2− . The resulting catalyst showed high activity and selectivity in the oxidation of sulfides to sulfoxides with H 2 O 2 as a green oxidant at room temperature. In addition, due to the presence of ammonium groups in the catalyst structure, water dispersibility of the catalyst was increased. More important, the catalyst was magnetically recovered and reused for up to six runs without any marked decrease of activity and selectivity. Finally, easy gramscale oxidation of methylphenyl sulfide as well as fast separation of catalyst and product makes the protocol economical and industrially applicable.
