Usage

General Description

4-Nitrobenzenediazonium toluene-4-sulphonate is a chemical compound that is used in the synthesis of various organic compounds. It is formed by the reaction of 4-nitroaniline with sodium nitrite and hydrochloric acid, followed by the addition of sodium toluene-4-sulfinate. 4-Nitrobenzenediazonium toluene-4-sulphonate is commonly used in organic chemistry as a diazonium salt, which can be further reacted with a variety of nucleophiles to form new carbon-carbon and carbon-nitrogen bonds. It is also used in the production of dyes, pharmaceuticals, and other industrial chemicals. However, it is important to handle this compound with care, as it is highly reactive and can be hazardous if not properly controlled.

A convenient approach to arenediazonium tosylates

Herein we present a mild, simple and environmentally friendly diazotization protocol of aromatic and heteroaromatic anilines into stable diazonium salts that surpass previously reported procedures. The reaction proceeds with tert-butyl nitrite in the presence of an equimolar amount or small excesses of p-toluenesulfonic acid in ethyl acetate, at room temperature. o-Phenylenediamines yield benzotriazolium tosylates. The resulting diazonium tosylates proved to be bench stable over a long period of time. In selected examples, diazonium salts were let to react with activated aromatic compounds including 2-naphthol and aniline derivatives into the corresponding azo dyes.

[3+2]-Cycloaddition of α-Diazocarbonyl Compounds with Arenediazonium Salts Catalyzed by Silver Nitrate Delivers 2,5-Disubstituted Tetrazoles

[3+2]-Cycloaddition of arenediazonium salts with diazo compounds (earlier exemplified only for trimethylsilyldiazomethane and 2,2,2-trifluorodiazoethane) has been developed to include a wide range of readily available α-diazocarbonyl compounds. The resulting 2-aryl-5-acyl-2 H -tetrazoles are of high value in medicinal chemistry.

Changes in major charge transport by molecular spatial orientation in graphene channel field effect transistors

Changes in major charge transport of graphene channel transistors in terms of the spatial orientation of adsorbed functional molecules were demonstrated. In contrast to the horizontally (physically) bound molecules, the vertically (chemically) bound molecules did not change major charge carriers of graphene channels, revealing the molecular orientation-dependent doping effects.
