Micellar catalysed and heteroaromatic base promoted rate enhancement of oxidation of an alicyclic alcohol in aqueous medium

Rate enhancement of ‘in water’ organic transformation by anionic‐nonionic mixed micelle

“…There are ample examples of this in the literature with time-to-time advancement of the same. [3][4][5][6][7][8] This experiment also witnesses such an advance step in the same micellar mediated reactions utilizing mixtures of micelle of non-ionic and anionic surfactants as reaction media. There are some reports in past records of analysing properties of mixed micelles by different techniques.…”

“…Kinetics of oxidation reaction in single micellar media has been studied before. [6][7][8][13][14] But mixed micelle has been introduced exceptionally with a newer version of aldehyde oxidation. Propanal, a small aldehyde, has been oxidised by Cr(VI) to propionic acid, useful in food preservation and pharmaceuticals, [15] in mixed micelle media of anionic surfactant (SDS) and non-ionic surfactant (TX-100) in a pseudo first order reaction condition at 30 ºC temperature.…”

A Review of some catalysts and promoters used in organic transformations

“…[117] L-glutamine derived γamino acids were effieient catalyst for nitroaldol condensation between aromatic aldehydes and nitromethane. [118] [11,119] Utilisation of micellar catalyst in oxidation kinetics is a research topic that we have performed for last two decades. Role of micellar catalyst in oxidation of aliphatic and aromatic alcohols, aldehydes, acids; sugars etc.…”

“…Most recent reports of oxidation of alicyclic alcohols, hydrophobic fatty alcohols and aldehyde are truly reported for the first time. [119][120][121] Role of mixed-micelle on oxidation kinetics have never been reported prior to the work of Acharjee et al [122] Another discipline of micellar catalyst deserved to be mentioned here is the designer surfactants, developed by Lipshutz et al The 1 st generation designer surfactant was a non ionic surfactant composed of vitamin E, sebacic acid and PEG 600, known as PTS (polyoxyethanyl-αtocopheryl sebacate). [123] The 2 nd generation designer surfactamt is an evolution of PTS, known as TPGS 750M (Polyoxyethanyl-α-tocopheryl succinate).…”

Mixed Micelles of Surface Active Ionic Liquid (SAIL)–Octylphenol Ethoxylate: A Novel Reaction Medium for Selective Oxidation of Toluene to Benzaldehyde

“…In normal micelles, the interior hydrophobic part is composed of the hydrocarbon chain, the first few methylene groups being known as palisade layer, whereas the surface of the polar heads faces water. A concentric shell of hydrophilic head groups with (1 – α ) N counter ions, where α is the degree of ionization and N is the aggregation number (number of molecules in micelles), is called Stern layer (Acharjee et al, 2019a, b; Saha et al, 2014). The dielectric constant of the micellar phase is generally much lower than that of water and hence this medium can solubilize many organic compounds, which have limited solubility in water (Dwars et al, 2005).…”
