General description

Dinitrobenzene is commonly used in industrial explosives containing ammonium nitrate. 1,4-Dinitrobenzene forms negative molecular ion M-· by electron capture or charge exchange.

Application

1,4-Dinitrobenzene was used in a study to evaluate the ionization mechanism and solvent effect by novel atmospheric pressure photoionization mass spectrometry in negative ion mode for analysis of some compounds. 1,4-Dinitrobenzene can be used in synthesis of dyes and dye intermediates.

Preparation Note

One gram of 1,4-Dinitrobenzene dissolves in 12,500 ml cold water, 555 ml boiling water and 300 ml alcohol.

The photostimulated intramolecular ortho-arylation reactions of bromoarenes linked with pendant phenoxy containing N-substituted tetrahydroisoquinolines in liquid ammonia afforded aporphine (54-82% yield) alkaloid derivatives via SRN1 reactions. This strategy was extended for the first time to the synthesis of a homoaporphine
