NEW METHOD FOR THE SYNTHESIS OF AMMONIUM SALTS OF OO′-ALKYLENEDITHIOPHOSPHORIC ACID AND OCTATHIOTETRAPHOSPHETANE. CRYSTAL STRUCTURE FEATURESS OF DIETHYLAMMONIUM SALT OF OO-PROPYLENEDITHIOPHOSPHORIC ACID

摘要

A new reaction of elemental phosphorus (P4) with elemental sulfur and 1,3-propylene glycol in the presence of different amines has been investigated. Ammonium salts of O,O′- alkylenedithiophosphoric acids have been observed as main products of the reaction. Octathiotetraphosphetane ammonium salts were formed as minor products. The reaction is characterized by a complete conversion of white phosphorus and is not accompanied by the release of hydrogen sulfide. The crystal structure features’s of diethylammonium salt of O,O′-propylenedithiophosphoric acid were determined using single crystal X-ray diffraction. Piperidinium salt of octathiotetraphosphetane in DMSO and DMF solutions possess significant antifungal activity against Candida albicans.
