Figure 3 shows a cychc voltammogram for compound 3H at a low-scan rate (see footnote 1). In all cases, starting with a cathodic scan, no reduction waves appear in the first scan, so neither l-chloro-2,4,6-trinitrobenzene (the Sn product), nor 1,3,5-trinitrobenzene (the Sn product), are initially present in the reaction mixtures. Figure 3a shows that, upon starting with an anodic scan, two well-defined waves at 0.68 V and 1.24 V are observed. When the anodic scan is followed by a cathodic scan, two waves, at 0.53 V and 0.56 V, are observed. These reduction waves correspond to l-chloro-2,4,6-trinitrobenzene (the Sn product) and 1,3,5-trinitrobenzene (the Sn product), respectively [23, 40]. 

When the anodic scan is reversed after the first oxidation wave (0.68 V) (Fig. 3b) only one reduction wave is obtained ( 0.53 V). Thus, the oxidation wave at 1.24 V appears to be connected with the reduction wave at —0.56 V. That, is to say, l-chloro-2,4,6-trinitrobenzene is obtained due to the oxidation of 3H (1,3) (o -cotnplex, the reaction), while 1,3,5-trinitrobenzene is derived from the oxidation of 3H (1,1) (o -complex, the reaction). 

Laval and Vignane reported the synthesis of the nitrotriazole (124) from the reaction of 3-nitro-1,2,4-triazole with 3,5-diamino-l-chloro-2,4,6-trinitrobenzene. The nitrotriazole (124) is a useful secondary high explosive, exhibiting high performance and a low sensitivity to impact.

By the nitration of l-chloro-3,4-dinitrobenzene with nitric acid in the presence of 40% oleum, at a temperature of 140-150°C a picryl chloride isomer, 1-chloro-2,4,5-trinitrobenzene, is formed. 

Among the chemicals that are only now slowly attracting attention are nitro-aromatic compounds and fiuorinated organics. Nitrobenzene in the ng/1 range and l-chloro-2-nitrobenzene in one order of magnitude lower concentrations are widely distributed in the German Bight, and musk xylene (l-fert-butyl-3,5-dimethyl-2,4,6-trinitrobenzene) and musk ketone (l-fert-butyl-3,5-dimethyl-...
