“…PA, 2,3-dipicolinic acid and 2,6dipicolinic acid was reported in oxidation of 2butanol [138] A variation of all the mentioned promoters was represented by Sar et al [141] Ghosh et al reported Phen and Bpy promoted oxidation reaction by permanganate in which Phen has shown highest accelerating capacity. [142] Bpy was found very much efficient promoter in oxidation of butanal by bivalent copper and chromium(VI) oxidation of acetaldehyde. [143,144] There are many more examples of such promoted reactions with great diversity of oxidants and reductants.…”

Catalytic processes are indeed greener modification as they completes in much shorter time with minimizing the need of external energy source with atom economy and high selectivity. In this article we presented a short review on utlisation of different catalysts such as ionic liquids, transition metal ions, nano particles, surfactants, amino acids etc. for C‐C coupling reactions to oxidation reactions. Stereoselective and regioselective transformations are also carried out using catalyst in organic synthesis. Use of catalyst in rate enhancement of oxidation reaction is of immense interest and a surplus rate increment is obtained by use of promoters.

“…(b) The distribution of reactants between water and "pseudo-micellar phase" in the micellar media also endorsed for acceleration of reaction kinetic [91,92]. (c) The hydrogen bonding or hydrophobic interaction between the nonionic micelles and anionic form of amino acid (in alkali medium) plays an important role [93].…”

“…Reproduced with permission from ref. [91] can be accelerated in water by the presence of just the surfactant above the CMC due to compartmentalization; in other cases, a catalyst (organocatalyst, transition metal complex as catalyst or metal nanoparticle is requested) and the micellar media have the role to promote the intimate contact between substrates and the catalyst (metal complex or metal nanoparticle), imparting specific selectivity both for the substrate and the product.…”

Surfactant is a special kind of amphiphilic compound composed of water-loving and hating parts. The remarkable physical properties like interfacial tension, wettability, emulsifying and dispersing ability make the surfactant accessible for numerous applications from laboratory to commercial products. In recent years, the commercial applications of surfactant have led to greater relevance on account of the environmental concerns and market pressures of this compound. The utility of surfactants in global market increases steadily since its formulation with several beneficial aspects in pharmaceutical, detergent, cosmetic, paint, food science, gas hydrate, nanotechnology, petroleum recovery, bioremediation, chemical transformation and drug delivery. This review briefly discusses the applied aspect of surfactants in diverse area as well as catalytic effect of micelle in organic reactions from the recent literature survey. The trend of increasing use of bioderived surfactants in the modern field of research is also considered in this report. The recent advancement of surfactant-based organic transformations has been emphasized with the role of surfactant aggregates in course of different organic reactions.

“…The kinetics and oxidation processes of pectates, 18 methyl cellulose, 19 alginates, 20 carboxymethyl cellulose, 21 chondroitin-4-sulfate 22 carbohydrates, and BTB 23 by potassium permanganate have been studied in basic solutions. However, the oxidation of methyl cellulose, 15 pectates, 24 carboxymethyl cellulose, 25 BTB, 26 N -(2-acetamido)imino diacetic acid, 27 poly(ethylene glycol), 28 2-butanol, 29 , 30 and mannitol 31 were investigated in acidic solutions. In these reactions, the pseudo-first-order plots were discovered to be reverse S-shape, and the reactions were found to proceed through free-radical intervention.…”

Kinetics and Mechanism Studies of Oxidation of Dibromothymolsulfonphthalein Toxic Dye by Potassium Permanganate in Neutral Media with the Synthesis of 2-Bromo-6-isopropyl-3-methyl-cyclohexa-2,5-dienone

The oxidation of 3′,3″-dibromothymolsulfonphthalein (DBTS) in neutral medium by potassium permanganate multi-equivalent oxidant has been studied spectrophotometrically. Pseudo-first-order plots showed inverted S-shape throughout the entire course of the reaction. The initial rates were found to be relatively fast in the early stages, followed by a decrease in the oxidation rates over longer time periods in the slow stage. Under pseudo-first-order conditions where [DBTS] ≫ 10 [MnO 4 – ], the experimental results showed a first-order dependence in [MnO 4 – ] and fractional-first-order kinetics in the [DBTS] concentration. The formation of 1:1 coordination intermediate complex prior to the rate-determining step was revealed kinetically. In addition, the intermediate species involving complexes of Mn(V) coordination has been detected. The oxidation product of DBTS was identified by Fourier transform infrared spectroscopy, ultraviolet–visible spectrophotometry, and gas chromatography–mass analysis. The obtained results indicated the formation of 2-bromo-6-isopropyl-3-methyl-cyclohexa-2,5-dienone as a derivative oxidation of DBTS.
