Recent advances on micellar catalysis in water

The Photoinduced Electrocyclization Reaction of Triphenylamine (TPA) in Sustainable and Confined Micellar Solutions: A Steady‐State and Laser Flash Photolysis Approach

“…[1] Furthermore, micellar media emerged in recent years as a sustainable alternative to traditional non-renewable feedstock derived solvents in organic synthesis. [2][3][4][5][6][7] In this context, an impressive range of both photochemical and photocatalyzed processes has been investigated under micellar conditions including, among the most recent examples, photo-Fries rearrangements, [8,9] decarboxylation of αarylpropionic esters [10] and photoredox catalyzed processes. [11][12][13][14][15][16] A significant attention has been also given to the use of photocyclizations as reaction model to investigate micellar systems, as an example, the conversion of 2-pyridylphenyl ketone into fluorenone-like derivatives was investigated in sodium dodecyl sulfate and Triton X-100 micelles by Favaro and co-workers, via both steady-state and time-resolved analyses [17] More recently, Petrov and co-workers described the photochromism of 7,4'-Dihydroxyflavylium/trans-chalcone system in the presence of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) as the surfactant.…”

“…Micelles were largely proved to alter (and, in most cases, to improve) rates, efficiency and the chemo‐, regio‐ and stereoselectivity of any kinds of chemical reactions, since their ability to stabilize either reactants or chemical intermediates, to concentrate the starting substrates within their small volumes as well as to significantly modify a wide range of physicochemical properties including redox properties, dissociation constants and ionization potentials [1] . Furthermore, micellar media emerged in recent years as a sustainable alternative to traditional non‐renewable feedstock derived solvents in organic synthesis [2–7] …”

Gemini and Bicephalous Surfactants: A Review on Their Synthesis, Micelle Formation, and Uses

“…Micellar catalysis using gemini surfactants has been applied in reactions of ester hydrolysis [143], chloromethylation [144], and nucleophilic and electrophilic substitutions [137]. Furthermore, the catalytic properties of these surfactants have favored the development of aqueous micellar catalytic processes, where the substitution of organic solvents for water is achieved, contributing to the development of more sustainable and environmentally friendly processes [145].…”

Structural investigation and application of Tween 80-choline chloride self-assemblies as osmotic agent for water desalination

“…At concentrations above the critical micelle concentration (CMC), the surfactant monomers aggregate to form micelles in order to minimize the free energy of the system. Micellar systems have widespread applications in food, biotechnology, chemicals, catalysis, and petroleum industries 11 – 13 . The interactions between micelles arising from electric double-layer repulsion can result in substantial deviation from ideal solution behavior, and consequently a remarkably elevated osmotic pressure.…”
