- INTERPHASE ANALYSIS IN THE CHEMISTRY OF ALIPHATIC NITRO COMPOUNDS. 1. ALKYLATION OF ALKALI METAL SALTS OF TRINITROMETHANE UNDER INTERPHASE CATALYSIS CONDITIONS IN SOLID PHASE-LIQUID SYSTEMS
-
Methylation of trinitromethane salts was studied under interphase catalysis conditions in a solid phase (a trinitromethane salt)-liquid (methyl iodide) system in the presence of interphase transfer catalysts - onium salts, cyclic and acyclic polyethers.The dependence of the yield of the methylation product - 1,1,1-trinitroethane - on the nature of the catalyst was also investigated, and based on this, catalysts were found, in whose presence the methylation process is realized more effectively than under homogeneous conditions.

- REACTION OF DINITROMETHYL COMPOUNDS WITH XENON DIFLUORIDE IN VARIOUS SOLVENTS
-
The products from the reaction of xenon difluoride with the potassium salts of a series of dinitromethyl compounds ( dinitromethane, trinitromethane, 1,1-dinitroethane, phenyldinitromethane) in methylene chloride, carbon tetrachloride, and acetonitrile were investigated.On the basis of the data from analysis by GLC and UV spectroscopy it was found that in most cases the reaction takes place with the participation of solvent molecules.The proposed reaction mechanism includes a stage of one-electron oxidation of the anion of the dinitromethyl compound by the XeF2 molecule to a dinitromethyl radical.

- REACTION OF 1,1-DINITROETHANE POTASSIUM SALT WITH XENON DIFLUORIDE
-
The potassium salt of 1,1-dinitroethane reacts with xenon difluoride in methylene chloride to form a mixture of products, i.e., acetic acid, 1-fluoro-1,1-dinitroethane, 1-chloro-1,1-dinitroethane, 1,1,1-trinitroethane, and 1,1-dinitroethane.The ratios of the yields depend on the reaction conditions.The proposed mechanism for the formation of the reaction products involves one-electron oxidation of the dinitroethane radical, which enters into reaction with the methylene chloride molecules and intermediate radical particles.
