- REACTION OF α-POLYNITROALKYL DERIVATIVES OF SULFUR AND SELENUM WITH HYDROGEN HALIDES AND HALIDE IONS
-
Hydrogen halides ( HCl and HF) react with α-polynitroalkylsulfides and α-polynitroalkylselenides as elctrophilic or as nucleophilic reagents depending on the conditions, forming accordingly products of electrophilic or nucleophilic substitution at the α-carbon atom.In contrast to this, halogen ions (Cl-, F-) always bond to the α-carbon.The use of dipolar aprotic solvents ad activators ( Lewis acids or strong mineral acids) facilitates the formation of products of nucleophilic substitution at the α-carbon.

- 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, trinitromethylation-dialkoxylation, trinitromethylation-diaryloxylation, and trinitromethylation-alkoxylation-aryloxylation. The mechanisms of reactions are proposed.

- 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.
