Due to the rapidity and the effectiveness of the method, the reduction of diazonium salts has been widely used to functionalize electrodes for sensor applications. However, the resulting organic film usually designed to provide complexing capabilities for the species to be determined could affect the sensor properties. The electrochemical reduction of 4methoxybenzene diazonium salt on graphite ...

We describe an original approach to graft molecularly imprinted polymers around gold nanorods by combining the diazonium salt chemistry and the iniferter method. This chemical strategy enables fine control of the imprinting process at the nanometer scale and provides water-soluble plasmonic nanosensors.

We present a new efficient two-step method to covalently functionalize hydride terminated silicon nanocrystals with nucleophiles. First a reactive chlorosilane layer was formed via diazonium salt initiated hydrosilylation of chlorodimethyl(vinyl)silane which was then reacted with alcohols, silanols and organolithium reagents. With organolithium compounds a side reaction is observed in which a d...

A general approach to the synthesis of novel boronated azo dyes derived from undecahydro-closo-dodecaborates as a convenient preparation of dye labeled for boron neutron capture therapy (BNCT) is described. The method focused on the synthesis of two classes of dye-labeled dodecaborate anions. One is the reaction of (CH3)4NB12H11NH3- with NaNO2 in acetonitrile/water to give its diazonium salt wh...

A novel series of sulpha/ substituted phenyl azo indoles is synthesised by the condensation reaction of N.phenacyl sulpha/ substituted phenyl amine with diazonium salt of sulpha/substituted benzene. They were characterized by IR, NMR and UV spectra and screened for their promising antituberculosis activity and antifertility activity. Keyword: indoles, sulpha/ substituted, drug, biological activ...

This communication reports a new approach to synthesize amphiphilic block copolymers. The copolymers with well-defined structures were synthesized by macromolecular azo-coupling reaction between the diazonium salt of aniline-functionalized PEG and the polymeric blocks with a terminal suitable for the azo-coupling reaction.

1. Conjugated bilirubin is conveniently determined by coupling with the diazonium salt of ethyl anthranilate. 2. This method has been used in the development of assays for UDP-glucuronyltransferase (EC 2.4.1.17), with bilirubin as substrate, in rat liver homogenates, microsomal preparations and partly purified fractions. 3. Chromatographic analysis suggests that bilirubin monoglucuronide is the...

A method for measuring serum glutamic oxalacetic transaminase activity is described, in which substrate concentrations are more nearly optimal than in previous colonmetric methods. By coupling the diazonium salt at a pH of 4.2, interference from a-oxoglutarate is negligible. Oxalacetate is produced at a linear rate to 180 l.U. Results correlate well with those obtained by a reference spectropho...

Nanosilica periodic acid (nano-SPIA) is found to be a new, powerful, and reusable heterogeneous catalyst for the rapid synthesis of 2-naphtholazo dyes via diazotization of aromatic amines and followsazo coupling with 2-naphthol under solvent-free conditions at room temperature by grinding. Eco-friendly, heterogeneous reaction conditions, high stability of diazonium salt, simple experimental pro...
