Synthesis and Crystal Structure of 2,3-Bis(dinitrofluoromethyl)-1,4-dioxane

For the first time the dinitromethyl group was modified to dinitrofluoromethyl group in the series of aliphatic polynitro compounds in the case of the reaction of 1,1,4,4-tetranitro-2,3-butanediol diacetate with ammonium fluoroxysulfate in the presence of sodium bicarbonate and ethylene glycol. Previously unknown 2,3-bis(dinitrofluoromethyl)-1,4-dioxane was synthesized. Its structure was determined by X-ray diffraction analysis.

Synthesis of 4,7-diaminopyridazino[4,5-c]furoxan

Abstract4,7-Diaminopyridazino[4,5-c]furoxan was synthesized by intramolecular cyclization of 3-cyanofuroxan-4-carbamidrazone obtained from 3,4-dicyanofuroxan and hydrazine.

Synthesis and properties of 1,2,4-triazolo[4,3-d]-1,2,4-triazolo-[3,4-f]furazano[3,4-b]pyrazines

New methods for the synthesis of 1,2,4-triazolo[4,3-d]-1,2,4-triazolo[3,4-f]furazano[3,4-b]pyrazines with functional substituents of various types are proposed and some properties of these compounds are studied.

Synthesis and some properties ofN-polynitromethyl derivatives of fused benzotriazoles

The procedures for the synthesis ofN-polynitromethyl derivatives of benzo[1,2-d;4,5d′]ditriazole-4,8-dione are described. Some chemical properties of the compounds obtained are investigated.

The synthesis of fused benzotriazoles based on hexaaminobenzene derivatives

New methods for synthesis of hexaaminobenzene are proposed and, based on this compound, previously unknown preparative procedures for obtaining fused benzotriazoles are developed.

Development of a new xymedone production technology

A new technology for preparing substance used in the burn treatment agent xymedone by interaction of ethanolurea with acetyl acetate in isopropanol medium in the presence of hydrochloric acid and subsequent neutralization of the resulting xymedone HCl with ammonia or alkaline solution is described. This technology was introduced into experimental production at the Federal State Unitary Science Research Institute “Kristall.”

Synthesis, properties, and structures of 5-nitroalkyl-5H-(1,2,3)triazolo[4,5-c]furazans

Methods for the synthesis of the first representatives of 5-nitroalkyl-5H-(1,2,3)triazolo[4,5c]furazans have been developed, and some of their properties have been studied.

1,1,4,4-Tetranitrobutane-2,3-diol and its derivatives. 5. Reaction of 1,1,4,4-tetranitrobutane-2,3-diol with formaldehyde; synthesis and crystal structure of 4,4-dinitro-2,3-dihydroxytetrahydrofuran

Abstract1,1,4,4-Tetranitrobutane-2,3-diol reacts with formaldehyde, forming 2,2-dinitropropane-1,3-diol or a cyclic ether — 4,4-dinitro-2,3-dihydroxytetrahydrofuran — as a function of the reaction conditions.
