General Description

2,7-Dinitrophenazine is a chemical compound consisting of a phenazine ring with nitro groups at the 2 and 7 positions. It is a yellow to orange crystalline solid that is insoluble in water. 2,7-Dinitrophenazine has been found to have various potential applications, including as an intermediate in the synthesis of pharmaceuticals and in the preparation of dyes and pigments. It is also used in the production of fluorescent brightening agents and as an intermediate in the manufacturing of other organic chemicals. However, it is important to handle this compound with care, as it is a potential explosive and is toxic if ingested, inhaled, or absorbed through the skin.

A under the microwave radiation in the aqueous phase catalytic synthesis of phenazine compounds

The invention discloses a method for catalytically synthesizing phenazine compounds in a water phase under microwave radiation, which comprises the following steps: adding a catalytic amount of catalyst ferric chloride or nickelous chloride, a cocatalyst lithium proline, a substrate substituted 2-haloaniline, a phase-transfer catalyst 4-butyl ammonium chloride, 4-butyl ammonium bisulfate or 4-butyl ammonium bromide, an inorganic alkali or organic alkali and water into a reaction vessel, putting into a microwave reaction instrument, reacting at certain temperature under certain power for some time, concentrating under reduced pressure, and purifying the product by column chromatography. The method for preparing phenazine compounds is friendly to the environment, simple to operate and high in efficiency. Compared with the prior art, the method has the advantages of obviously higher reaction speed than conventional heating, mild reaction conditions, high yield, high safety, low cost and environment friendliness, and is simple to operate.

Benzenesulphenanilidyl Radicals. Part 3. Reactions of 4'-Substituted Benzenesulphenanilides with t-Butoxyl Radicals

Decomposition products of the 4'-substituted benzenesulphenanilidyl radicals (2a, b, d, and e), generated from the corresponding benzenesulphenanilides (1) with t-butoxyl radicals, have been investigated in benzene, acetonitrile, and acetone.Results indicate that the decomposition modes exhibited by these radicals are not essentially influenced by variation of the solvent polarity; comparison of the findings with present and previous results from oxidation of (1) with lead dioxide show that the chemical reactivity trend displaced by the thioaminyls (2) can be greatlyinfluenced both by the reaction medium and the 4'-substituent.Evidence is presented that the benzenesulphenanilides (1b) and (1e) react in acetone in the presence of di-t-butyl hyponitrite to give products ascribable to homolytic substitution at the sulphenanilide sulphur by acetonyl radicals.
