The acidities of 12 substituted phenols (pKBNa relative to the pKBNa of HClO4) and the formation constants of the corresponding homocomplexes, KAHA, in benzonitrile have been determined from e.m.f. measurements. Comparison with previous results reveals that the stability of homocomplexes increases in aprotic solvents in the order acetonitrile ...

Phenol and substituted phenols AOPs remediation
Journal of Hazardous Materials, 2005The oxidation of phenol and two substituted species (4-nitrophenol and 4-chlorophenol) has been carried out by means of the O3, UV-vis, O3+UV-vis, TiO2+UV-vis, O(3)+UV-vis+TiO2 and O3+TiO2 systems. From UV-vis experiments, the quantum yield of these organics has been calculated (0.018, 0.005 and 0.017 mol per Einstein for phenol, 4-nitrophenol and 4 ...

Phenol Peeling and the History of Phenol Peeling
Clinics in Plastic Surgery, 1998Historically, phenol peeling has been embraced by plastic surgeons as the method of choice for improving the appearance of coarse facial rhytides. The principal advantage of phenol peeling is its predictability: it requires no pretreatment regime. This article details the technical aspects of phenol peeling, its uses and limitations, as well as methods

We report asymmetric dearomatization of phenols using Ag carbenoids from α-diazoacetamides. The Ag catalyst promoted intramolecular dearomatization of phenols, whereas a Rh or Cu catalyst caused C-H insertion and a Büchner reaction.

Carboxylation of Phenols with CO2 at Atmospheric Pressure.
Chemistry, 2016A convenient and efficient method for the ortho-carboxylation of phenols under atmospheric CO2 pressure has been developed. This method provides an alternative to the previously reported Kolbe-Schmitt method, which requires very high pressures of CO2 ...
