An efficient mixed micellar strategy for the catalytic oxidation of benzyl alcohol by diperiodatoargentate(iii) in aqueous media

“…The concentration at which the first break occurs should correspond to the CMC, and the horizontal portion of this plot indicates that micelle-like aggregates are present. 48…”

Influence of Chain Length and Concentration-Dependent Morphological Switching on Oxidation of Aromatic Alcohols in a Micellar Environment

“…The knowledge of critical micelle concentration (CMC) is essential in terms of the self-aggregation characteristic of surfactants by which micelle-like nanosized aggregates are produced in aqueous media. − In recent years, the unique catalytic activity of surfactants has long been gaining considerable attention from synthetic organic chemists, since in aqueous micellar media, the majority of organic reactions are accomplished with better solubilization, extensive reaction rate, and greater degree of product selectivity. − A lot of organic reactions are performed in an aqueous micellar medium to reduce the environmental impact of traditional organic synthesis. − Along with the elimination of hazardous solvents from organic synthesis, the use of water as a reaction medium also offers chemical processes simplified operations, allowing for mild reaction conditions. The oxidation reaction is one of the most studied organic reactions, which produces a large number of precursor compounds with significant industrial applications. , The study of the micelle-mediated oxidation kinetics of numerous substrates led by higher-valent metal ions has long been substantially illuminated. − On account of the high reduction potential value ( E 0 ), metals like Cr­(VI), , Mn­(VII), V­(V), , Cu­(III), − Ce­(IV), − Fe­(III), Co­(III), and Ag­(III) , have significant strength to oxidize many organic substrates. Chromium­(VI) appeared as a renowned oxidant, used for various oxidation processes in organic synthesis over a long period, for its distinct speciation and high E 0 (1.33 V) in acidic conditions despite having detrimental effects, such as the harmful impact of chromium drops after oxidation, since it itself reduces to Cr­(III), which is kinetically inert and nontoxic.…”

A promising mixed micellar approach to tune the oxidation of isoprenol by diperiodatoargentate(iii) in aqueous media

“…17 By virtue of numerous beneficial aspects and following the direction of nature, our group have long been utilizing aqueous surfactant solution to perform organic reactions, especially single step oxidative transformation in water media. 18,19 In order to produce crucial organic molecules through a simple oxidation process, transition metals of higher oxidation states (like Cr(VI), [20][21][22] V(V), 23,24 Ce(IV), 25 and Cu(III) 26 ) are the best choice as oxidizing agents over long periods. In our recent work, we have studied the oxidizing potential of Cu(III) following the kinetics of 1-propanol and 1,3-propanediol oxidation using mixed micellar media comprised of Triton X-100 and cetylpyridinium chloride (CPC).…”
