Synthesis and structures of nitroxyalkyl methylphosphonates

The reactions of ethylene glycol mononitrate and glycerol 1,3-dinitrate with methylphosphonic dichloride afforded new nitroxyalkyl methylphosphonates.     

Synthesis and fluorination of nitro-substituted thionocarbonates

Thiocarbonylchloride reacts with -nitroalcohols yielding symmetrical thionocarbonates. Transesterification of bis(2-fluoro-2,2-dinitroethyl)thioncarbonate affords alkyl 2-fluoro-2,2-dinitroethylthionocarbonates. Fluorination of these thionocarbonates yields the corresponding difluoroformals.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 2, pp. 375–376, February, 1993.     

Peculiarities of the nitration of secondary polynitroalkanes

Conclusions In the interaction of salts of 1,1,1,3,5,5,5-heptanitro- or 1,5-difluoro-1,1,3,5,5-pentanitropentanes with nitrating systems based on HNO₃, 1,1,1,3,3,5,5,5-octanitro- or 1,5-difluoro-1,1,3,3,5,5-hexanitropentanes, 1,1,1,5,5,5-hexanitro- or 1,5-difluoro-1,1,5,5-tetranitropentan-3-ones, the O-bis-(2,2,2-trinitroethyl)nitromethyl ether of bis(2,2,2-trinitroethyl)carboxime or the O-bis(2-fluoro-2,2-dinitroethyl)nitromethyl ether of bis(2-fluoro-2,2-dinitroethyl)carboxime are formed. The ratio of the reaction products depends on the composition of the nitrating system. The data obtained permit us to consider that the nitrating reagent is a nonionized form of HONO₂ or AcONO₂.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1357–1361, June 1986.     

Synthesis and properties of fluoronitroalcohols. Report 5. 1,5-difluoro-1,1,5,5-tetranitropentan-3-ol

Conclusions 1,5-Difluoro-1,1,5,5-tetranitropentan-3-ol was obtained by reduction of 1,5-difluoro-1,1,-5, 5-tetranitropentan-3-one with NaBH₄ in the presence of BF₃ etherate.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 398–401, February, 1986.     

Synthesis of esters of 3-fluoro-3-nitroacrylic acid

Conclusions The reaction of 1,3-difluoro-1,1,3,3-tetranitropropane with alkanols was used for the preparation of alkyl esters of 3-fluoro-3-nitroacrylic acid. 1,3-Difluoro-1,3,3-trinitro-1- propene and 1,3-difluoro-1,3-dinitro-2-alkoxy-1-propene were also isolated as intermediates.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 709–711, March, 1989.     

Synthesis and structure of o-bis(2-fluoro-2,2-dinitroethyl)-nitromethyl ester of 2′-fluoro-2′, 2′-dinitroethyl-2″-fluoro-2″-nitroethylenecarboxime

Conclusions The product of conversion of O-bis(2-fluoro-2,2-dinitroethyl)nitromethylbis(2-fluoro-2,2-dinitroethyl)carboxime in methanol or ether is O-bis(2-fluoro-2,2-dinitroethyl)nitromethyl-2-fluoro-2,2-dinitroethyl-2'-fluoro-2-nitroethylenecarboxinie, the structure of which has been established by x-ray diffraction analysis.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2019–2021, September, 1987.     

The covariant approach in the dynamic theory of resonant X-ray diffraction

The main equations of the dynamic theory of X-ray synchrotron radiation resonant diffraction were obtained based on direct (coordinate-free) methods of tensor calculus.
