A 2,2 the [...], 4,4 the [...], 6,6 the nitro-six [...] process for the preparation of diphenyl ethylene

The present invention relates to a 2,2',4,4',6,6'-hexanitro diphenylethylene preparation method, which comprises that: (1) 2,4,6-trinitrotoluene and sodium hypochlorite are subjected to a reaction in a reaction solvent to prepare hexanitro bibenzyl, wherein the reaction solvent is a mixing solution of ethanol and benzene, and (2) the hexanitro bibenzyl and bromine are subjected to a reaction in a reaction solvent to prepare 2,2',4,4',6,6'-hexanitro diphenylethylene, wherein the reaction solvent is a mixing solution of dichloroethane and pyridine, the reaction solutions in the step (1) and the step (2) can be filtered to collect the filtrates, and the filtrates can be used as the reaction solvent of the corresponding steps. Compared with the preparation method in the prior art, the preparation method of the present invention has the following characteristics that: the coupling reaction solvents can be recycled, the solvent loss in the dehydrogenation reaction is less, and the pyridine consumption is less.

Facile and efficient reductive homocoupling of benzyl and aryl halides catalyzed by ionic liquid [C12mim][CuCl2] in the presence of metallic zinc and copper

A facile and efficient synthesis of bibenzyl and biaryl derivatives by reductive homocoupling reaction is described. Treatment of benzyl and aryl halides with metallic zinc and copper powder in the presence of a catalytic amount of [C12mim][CuCl2] under ligand- and base-free conditions gives the corresponding bibenzyls and biaryls in good to high yields. The product can be isolated by a simple extraction with organic solvent, and the catalytic system can be recycled or reused without any significant loss of catalytic activity.

Production of hexanitrostilbene (HNS)

A process for the manufacture of 2,2', 4,4', 6,6-hexanitrostilbene (HNS) from dipicrylethane (DPE) or trinitrotoluene (TNT) which consists of oxidizing DPE or TNE substrate in the presence of an aprotic solvent and a basic salt of a carboxylic acid. The acid preferably consists of an ammonium or an alkali metal salt of a monocarboxylic or a dicarboxylic acid. The reaction step consists of heating the substrate and salt dissolved in the solvent to between 15° and 50° C., and contacting the reaction mixture with dry air or oxygen for up to 2 hours. The HNS product is precipitated out by quenching the reaction mixture in acidified water, and is optionally purified by washing first in methanol and then in acetone.
