The Influence of Solvents on the Alkylation of Carboxylate Phosphabetaines with Alkyl Iodides

The new alkylation reactions of a series of mono- and dicarboxylate phosphabetaines with methyl and ethyl iodides in different solvents have been studied. These reactions have afforded stable compounds: iodine-containing salts of phosphonium with different structure.

5-Amino-Substituted Derivatives of 4-Nitrofurazane: Synthesis,Structure, and Biological Activity

New amination reactions of 5-chloro-4-nitrobenzofurazane with different amines were studied. The reactions of 5-chloro-4-nitrobenzofurazane with 2,4,6-trichloro-, para-acetyl-, and para-carboxyethylanilines gave the products of aromatic nucleophilic substitution of the chlorine substituent in the nitrogenous heterocycle, the composition and structure of which was established by chemical, physical, and physicochemical methods and X-ray diffraction analysis. The thermal stability was studied by synchronous thermogravimetry and differential scanning calorimetry (TG?DSC). The synthesized compounds showed a high antibacterial and antimycotic activity against human and animal pathogenic microflora.
