Kundu, Bidyut Kumar; Das, Mriganka; Ganguly, Rakesh; Bhobe, Preeti A.; Mukhopadhyay, Suman published the artcile< Role of zeolite encapsulated Cu(II) complexes in electron transfer as well as peroxy radical intermediates formation during oxidation of thioanisole>, Name: 2-(Phenylthio)ethanol, the main research area is copper complex encapsulated zeolite sulfoxidation catalyst; electron transfer copper complex encapsulated zeolite sulfoxidation catalyst; peroxy radical copper complex encapsulated zeolite sulfoxidation catalyst.
Zeolite encapsulated host-guest complexes [CuL(NO3)@Y], and [CuL2@Y] (where, HL is 1-[(3-dimethylamino-2,2-dimethyl-propylimino)-methyl]-naphthalen-2-ol, I) have been synthesized and characterized by XRD, FTIR, Raman, TEM, XPS, UV-DRS, BET, EXAFS, and EPR spectroscopy. These complexes were used as heterogeneous catalysts for the oxidation of thioanisole, di-Ph sulfide, and 2-phenylthioanisole to produce sulfoxides analogs. H2O2 shows superior conversion efficiency and product selectivity over other common oxidants, viz tert-Bu hydroperoxide (TBHP), urea hydrogen peroxide (UHP) and di-tert-Bu hydroperoxide (DTBP). Formation of thermally stable copper hydroperoxo intermediate, which is to be believed as rate determining step in past few years, has been well proven. Besides that, for the first time, we have established that the oxidation process is not only going through by the generation of Cu(II)-OOH species but there is a considerable role of electron transfer (ET) mechanism also. Further, better TON value and recyclability make the encapsuled heterogeneous complexes more useful than that of homogeneous analogs.
Journal of Catalysis published new progress about Crystal structure (of CuL(NO3) and CuL2 complexes). 699-12-7 belongs to class alcohols-buliding-blocks, and the molecular formula is C8H10OS, Name: 2-(Phenylthio)ethanol.
