We investigated the effects of solvent composition, acidity and temperature on the switch between heterolytic and homolytic mechanisms in the course [...]

Dediazoniation of 1-naphthalenediazonium tetrafluoroborate in aqueous acid and in micellar solutions

Posted on by antiox@uvigo.es

We have measured the rates and product yields of dediazoniation of 1-naphthalenediazonium (1ND) tetrafluoroborate in the presence and absence of sodium dodecyl sulfate (SDS) micellar aggregates by employing a combination of UV–vis spectroscopy and high-performance liquid chromatography [...]

Micellar effects on the reaction between an arenediazonium ion and the antioxidants gallic acid and octyl gallate

Posted on by antiox@uvigo.es

The effect of sodium dodecyl sulfate (SDS) micelles on the reaction between the 3-methylbenzenediazonium (3MBD) ion and either the hydrophilic antioxidant gallic acid (GA) or the hydrophobic analogue octyl gallate (OG) have been investigated as a function of pH [...]
