“…Potassium triiodopyrazolate or triiodoimidazolate was prepared in situ by reacting a suspension of triiodopyrazole or triiodoimidazole with potassium hydroxide in acetonitrile until a clear solution was achieved. The dichloro compounds, 1,3-dichloro-2-nitrazapropane, 1,5-dichloro-2,4,-nitrazapentane, 1,7-dichloro-2,4,6-trinitro-2,4,6-triazaheptane, and 1,3-dichloro-2,2-dinitropropane, were synthesized according to known methods. The energetic-bridged triiodopyrazoles or triiodoimidazoles ( 1 – 8 ) were synthesized by adding the dichloro compounds to acetonitrile solution of potassium triiodopyrazolate or triiodoimidazolate, respectively.…”

Energetic bridged triiodopyrazoles and triiodoimidazoles were designed and synthsized by reacting potassium triiodopyrazolate or triiodoimidazolate with corresponding dichloro compounds. All compounds were fully characterized by H andC NMR spectroscopy, IR spectroscopy, and elemental analyses. The structure of compound 1 was further confirmed by single-crystal X-ray diffraction. All of the compounds exhibit good thermal stability with decomposition temperatures between 199 and 270 °C and high densities ranging from 2.804 to 3.358 g/cm. The detonation performances and the detonation products were calculated by CHEETAH 7. Compound 3 (D = 4765 m s; P = 17.9 GPa) and compound 7 (D = 4841 m s; P = 18.5 GPa) show comparable detonation pressure to TNT, and high iodine content makes them promising as energy and biocides storage compounds.

Trinitromethylation reactions of chloro-1,3,5-triazines

Reactions of chloro 1,3,5 triazines with trinitromethane salts were studied. Depending on conditions, trinitromethane salts used and special additives, six types of 2,4,6 trichloro 1,3,5 triazine trinitromethylation reactions were revealed, namely, bis trinitromethylation-nitro nyloxylation, bis trinitromethylation-amination, bis trinitromethylation-hydroxylation, tri nitromethylation-dialkoxylation, trinitromethylation-diaryloxylation, and trinitromethyl ation-alkoxylation-aryloxylation. The mechanisms of reactions are proposed.Polynitromethyl 1,3,5 triazines are of interest as ener getic materials as well as intermediates in synthesis of the latter 1 and bioactive compounds. 2,3 To date the known synthetic methods for polynitromethyl 1,3,5 triazines are based on the building of 1,3,5 triazine cycle from the moi eties carrying polynitromethyl group (through the cyclo trimerization of polynitro acetonitriles and imido esters 4-7 ) either on generation of trinitromethyl group in 1,3,5 tri azine derivatives (the nitration of methyl 1,3,5 triazines 8 and the destructive nitration of dicarboxymethyl deriva tives of 1,3,5 triazine 6,9 ). To synthesize bis and mono trinitromethyl 1,3,5 triazines with various substituents on the ring, the method has been proposed that is based on replacing trinitromethyl groups in trinitromethyl 1,3,5 triazines under the action of nucleophilic reagents. 10-15 As yet there are no literature data on the routes to tri nitromethyl 1,3,5 triazines involving nucleophilic re placement of chlorine atoms in chloro 1,3,5 triazines re acted with trinitromethane salts. In the comprehensive reviews on the chemistry of 1,3,5 triazines 16-19 and in the review papers on the synthesis of 1,3,5 triazine derivatives exploiting chloro 1,3,5 triazine reactions, 20-23 no men tion has been made of the chloro 1,3,5 triazine reactions with trinitromethane salts. This work attempts to general ize the results obtained while studying chloro 1,3,5 tri azine trinitromethylation with trinitromethane salts (the results mostly belong to 1980´s-90´s but could not be reported earlier). Results and DiscussionTrinitromethylation is a bimolecular nucleophilic sub stitution reaction that was studied in detail over a range of aliphatic halogenated compounds. 24-26 In N. D. Zelinsky Institute of Organic Chemistry, Russian Academy of Sci ences, these works were initiated in 1953, for a long period of time being headed by S. S. Novikov. Trinitromethyl anion is ambident, so generally, its interaction with halogenated organic compounds (if occurs) may proceed giving two types of products, i.e., trinitromethyl deriva tives (C alkylation) and dinitromethanenitronic acid es ters (O alkylation). 24-27 Nitronic esters (with rare excep tion 28 ) are unstable and highly susceptible to decom position. 24-26In its chemical properties, 2,4,6 trichloro 1,3,5 tri azine (cyanuric chloride (CC)) 17 is similar to acid chlo rides. The latter interact with polynitro compound salts to yield unstable mixed nitronic anhydrides. 29,30 This is ex actly...

“…Attempts to prepare 2,2,2-trinitrobromoethane from the alcohol were unsuccessful using a variety of brominating agents. 4 The nitration of 2,3dibromopropene has been reported to give 1,2-dibromo-I, 1-dinitroethane, 1, l-dinitro-2-bromoethane, and 2nitro-2,3-dibromopropanoic acid. 6 The (3-iodo and -fluoro derivatives of polynitro compounds have not been reported.…”
