Synthesis, Structure AXD Properties of N-Acidylated Amides of Phosphoxus Acids (IV) and Their Thio-Derivatives

This report presents the studies on various methods of obtaining, structure, and chemical properties of N-acidylated amides and thiamides of four-coordinated phosphorus atom acids expressed by a general formula The yield of compounds (I) is greatly affected by the nature of X and Y atoms, so there is no universal method of synthesis for them. The optimal methods of obtaining of the compounds I have been found. The structural investigations of the compounds (I), their alkaline salts, and their alkaline salt complexes with crown-ethers has been carried out using the IR, 1H, 31P and 13C NMR, X-ray and mass-spectroscopy.
