3,5-Dichlorophenyl
diazonium tetrafluoroborate (3,5-DClPDT), sodium
They found that the electrochemical reduction of [NO2PhEImMFc][TFSI] in acidic media containing sodium nitrite could lead to the in situ formation of the corresponding
diazonium, in the vicinity of the electrode, and subsequently the grafting of redox based IL onto the electrode surface.
After 40 min of continuous stirring, the suspension of
diazonium salt was added with cold solution of N,N-bis(2-hydroxyethyl)aniline (0.80 g, 4.4 mmol), which was previously dissolved in absolute alcohol, followed by the addition of anhydrous sodium acetate (3 g).
The main aim of this method is measurement of wave length of azo-dye which is formed by the reaction of 1-naphthylamine with
diazonium salt, formed by the reaction of sulphanilic acid with nitrous acid (Figure 2A) [43].
Spectrophotometric determination of uric acid in urine based-enzymatic method uricase with 4-Aminodiphenylamine
diazonium sulfate (Variamine Blue RT Salt).
Fragoso and O'Sullivan also reported a markedly more robust attachment based on reduction of individual
diazonium moieties and showed it to be significantly more stable than even dithiol attachment [25].
The
diazonium solution of 4 previously prepared was added dropwise over 1 hour, and then 15 mL of sodium acetate solution (10%) was added to the mixture.

It enters directly into epithelial cells of the colon from blood circulation, where MAMA produces reactive oxygen species and methyl
diazonium ions, responsible for the methylation of DNA and modification of nucleic acids and histones.
This study reports a simple FI spectrophotometric method for the determination of ANTU in natural waters, based on the conversion of nitrite into nitrous acid, subsequent diazotization of sulphanilic acid, and formation of the
diazonium salt.
Electrochemical transformations of [Fe.sub.3][O.sub.4] nanoparticles, carbon-coated nanoparticles, and iron nanoparticles coated with a layer of carbon and
diazonium salts from the surface of the CPE under its cathodic and anodic polarization have been studied.
Then, the mixture was cooled at a temperature from zero to -4[degrees]C, sodium nitrite (0.28 g, 4 mmol) in 2 mL of water was added portionwise at a temperature of -4[degrees]C to form the corresponding
diazonium salt 2, and the
diazonium salt formed was added to a mixture of 4-(substituted imino)pentan-2-one derivatives 3 (2 mmol) [27] in ethanol (15 mL) slowly under the same temperature allowing the mixture to stir at room temperature for an additional 3 hours.
