On October 1, 2020, Blanco, E.; Sepulveda, C.; Cruces, K.; Garcia-Fierro, J. L.; Ghampson, I. T.; Escalona, N. published an article.Product Details of 578-58-5 The title of the article was Conversion of guaiacol over metal carbides supported on activated carbon catalysts. And the article contained the following:

The preparation and use of new supported transition metal carbides as catalyst for the conversion of guaiacol was studied. Several metals (Mo, Re, Ru, Ni, Fe, and Cu) were impregnated over activated C and carburized under a mixture of H2/C2H4 at 700°. Catalysts were characterized by XRD, N2 physisorption, XPS, CO chemisorption, and TPR-MS. Evidence for carbide formation was obtained in the case of Mo, Re, Ni and Ru, based primarily on CO formation during the TPR-MS anal. Carbides were mainly active for primary guaiacol conversion to phenol and catechol through demethoxylation and demethylation. Completely deoxygenated products such as benzene and cyclohexane were also formed. The highest selectivity in benzene was obtained for the Re-TPR catalyst while Ni-TPR was the most hydrogenative one. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Product Details of 578-58-5

Lakouraj, Moslem M.; Hasantabar, Vahid published an article in 2011, the title of the article was Alumina-supported monoperphosphoric acid for selective oxidation of sulfides to sulfoxides.Synthetic Route of 53136-21-3 And the article contains the following content:

A selective oxidation of aromatic and aliphatic sulfides to the corresponding sulfoxide was carried out by using POCl3/H2O2 and alumina-supported phosphorus oxychloride(POCl3) and hydrogen peroxide. It was suggested that the active oxidizing agent formed in-situ is phosphoroperoxoic acid [i.e., monoperphosphoric acid P(O)(OH)2(OOH)]. The synthesis of the target compounds was thus achieved by a procedure for the oxidation of sulfides to sulfoxides without over-oxidation to sulfones. It is noteworthy that the reaction is clean and tolerates oxidatively sensitive functional groups and the sulfur atom is selectively oxidized. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Synthetic Route of 53136-21-3

On July 22, 2015, Capozzi, Maria Annunziata M.; Terraneo, Giancarlo; Cavallo, Gabriella; Cardellicchio, Cosimo published an article.Application of 53136-21-3 The title of the article was The search for exceptions in the highly enantioselective titanium catalysed oxidation of aryl benzyl sulfides. And the article contained the following:

After the discovery of a few cases of lower enantioselectivity in the oxidation of aryl benzyl sulfides with hydroperoxides in the presence of a complex between titanium isopropoxide and (S, S)-hydrobenzoin, a screening of the oxidation of new substrates that are related to the structures that gave low ee values, was performed. From this screening, we confirmed that only a few sulfides remain as exceptions within a framework of exceptionally high stereoselectivity of the oxidation reaction. Moreover, the exceptions are clearly identified and are connected to particular coordinating moieties present on the aryl groups. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Application of 53136-21-3

On September 30, 2020, Parnian, Rouhallah; Soleimani, Ebrahim; Bahrami, Kiumars; Ghorbani, Somayeh published an article.Related Products of 53136-21-3 The title of the article was Ag@CeO2 nanoparticles with “rice ball” configuration as an efficient and heterogeneous nanocatalyst for the selective oxidation of sulfides to sulfones with 30% H2O2. And the article contained the following:

Ag@CeO2 with a rice-ball configuration as a heterogeneous and highly efficient catalyst was described for activation of H2O2 in the selective oxidation of aromatic and aliphatic sulfides to their corresponding sulfones I (R1, R2 = n-Bu, Ph, 4-ClC6H5, etc.). Ag nanoparticles in the CeO2-Ag interface increase the oxygen vacancy defects on the surface of CeO2and oxygen vacancy defects promote the reduction of Ce4+ to Ce3+ to keep the electroneutrality. Generated Ce3+ species act as the active sites in the interface of CeO2-Ag to promote the oxidation of sulfides to sulfones. Compatibility with various aromatic and aliphatic sulfides, excellent selectivity, high yield of product, simple exptl. procedure, and mild reaction conditions are some of the precious advantages of Ag@CeO2/H2O2 catalyst system. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Related Products of 53136-21-3
