Abstract

Mixed micelle is an emerging strategy, with the potential to perform the organic reaction in aqueous phase, has been employed in oxidation of benzyl alcohol by diperiodatoargentate(III) in alkaline media....

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

“…In light of this, the CMC of DPCl is lower in water, suggesting that reactants interact with it and that submicellar aggregates may develop. , These occurrences were outlined by water depletion at the reaction center, substrate-induced micellization, and the interaction of substrate with the quaternary ammonium sites of the surfactant . The stronger π–π interaction between the pyridinium ring of cationic surfactants and the aromatic ring of substrates may be the plausible reason behind the rate acceleration of the studied oxidative transformation in both micellar media . It is noticeable that the cation−π interaction could also be a leading factor for solubilization of aromatic alcohols in the micellar phase .…”

“…The upfield movement of the protons of the CPCl and DPCl surfactants together with substrate protons is clear evidence of the greater solubilization of the substrate in the micellar confinement. An earlier report suggests the possibility of π−π interaction between the aromatic rings of the substrate and the surfactants, 44 which would raise the electrical density of the protons in the aforementioned surfactants. This is the vital cause behind the stronger encapsulation of the substrate in the micellar stern layer.…”

“…47 The stronger π−π interaction between the pyridinium ring of cationic surfactants and the aromatic ring of substrates may be the plausible reason behind the rate acceleration of the studied oxidative transformation in both micellar media. 44 It is noticeable that the cation−π interaction could also be a leading factor for solubilization of aromatic alcohols in the micellar phase. 58 The apparent rate enhancement An upsurge in the rate of oxidation with and increase in alkyl chain length of the studied surfactants from C 12 (DPCl) to C 16 (CPCl) can be attributed to increasing interface (due to increasing number of micellar aggregates) and hydrophobicity, which aid in solubilization of substrate molecules at the micellar interface.…”

Insights into the micellar catalysed efficient oxidation of 2- and 3-pentanol by cerium(iv) in a greener medium of SDS and STS

“…6,7 In our recent works, we have investigated the catalytic efficacy of single micelle and mixed micelle in the oxidation of several organic substrates at different micellar compositions along with their physiochemical properties using different techniques including conductivity, dynamic light scattering (DLS), and spectrofluorimetry. 8,9 There have been various studies on the oxidation of alcohols using various transition metal oxidants such as Cu( iii ), 10 Ag( iii ), 11 Cr( vi ), 12,13 V( v ), 14 and Mn( vii ). 15 In this research, we considered two isomeric alcohols (2-pentanol and 3-pentanol), which differ in symmetry, i.e.…”
