Thermal decomposition of energetic compounds, 1,4-dmitroimidazole [638-640], l-nitro-3-(p,p,P-trinitro-cthyl)-4,5-dinitroiminoimidazolidinc-2-onc [641] and its 4-nitroiminoimidazole [642], l-dinitromethyl-3-nitro-l,2,4-triazole derivatives [643], and C-nitro- and /V-nitro-1,2,4-triazoles [644-646], has been studied. The critical temperature of thermal explosion of imidazole derivative is 155.7°C [641],... [Pg.61]

Both 1-methyl-4- and l-methyl-5-chloroimidazoles can be nitrated in sulfuric acid. Exhaustive nitration of imidazole in mixed acids yields in succession 4-mono-, 4,5-di-, and 2,4,5-trinitroimidazole. With dinitrogen tetroxide in acetonitrile 4-substituted imidazoles with electron-withdrawing substituents yield a mixture of 5- and 2-nitro derivatives." Nitrations at C-2 are most unexpected. The nitration of 4-(4 -alkoxyphe-nyl)imidazoles with 3-4 M nitric acid occurs ortho to the alkoxy group and in the imidazole 5-position. With concentrated nitric acid di- and trinitro compounds are formed." ... [Pg.304]

Ipso nitration in iodoimidazoles has been reported." Even iodine atoms at C-2 can be replaced in nitric acid, while 4-iodo groups are displaced in nitric-sulfuric acid mixtures. With concentrated nitric acid the trinitro-imidazole 120 is formed (Scheme 29), and this is unexpected in view of the... [Pg.304]
