Reaction of the sodium salts of RC(S) NHP(S)(O-i-Pr)2 (R = Ph, HLI; PhNH, HLII; 2-MeC6H4NH, HL III; 2,6-Me2C6H3NH, HLIV; 2,4,6-Me3C6H2NH, HLV) or Z[NHC(S)NHP(S)(O-i-Pr)2]2 (Z = o-C6H 4,H2LVI; 1,2-CH2CH 2,H2LVII) with PPh4Br in 96% aqueous EtOH leads to the compounds of formulae PPh4LI-V and (PPh4)2LVI,VII. Compounds obtained were investigated by 1H and 31P{1H} NMR spectroscopy, ES mass spectrometry, and microanalysis. Recrystallization of PPh4LI from an aqueous EtOH solution (1:1, v/v) leads to the formation of PhC(S)NHP(O)(O-i-Pr)2 (HQ). The crystal structure of HQ reveals to be a polymorph to the previously reported structure.

The structure and intramolecular processes in solutions of N-(thio)phosphoryl(thio)benzamides were studied by 1H, 13C, and 31P NMR spectroscopy. Analysis of the NMR data confirmed the strong tendency of these compounds to tautomerism in solution. The amide form with trans orientation of the NH proton and the C=O(S) group with respect to the C-N bond was shown to be preferred. The free energies of activation of tautomerization of the amide forms were determined.

Electrolytic reduction of N-thiophosphorylated thioamides proceeds in two stages.One-electron transfer results in formation of radical anions, are stabilized via reaction with cations of the supporting electrolyte and via formation of dimeric compounds.Th
REACTIONS OF N-PHOSPHORYLATED AMIDES AND THIOAMIDES WITH ALKYL HALIDES

N-Phosphorylated thioamides and also their alkali-metal salts are easily alkylated by alkyl halides at the sulfur atom of the thiocarbonyl group, and in this process the reactivities of the alkyl halides decrease in the sequence: primary>secondary>tertiary. N-Phosphorylated amides do not react with alkyl halides, whereas their alkali-metal salts form easily hydrolyzable products of alkylation at the sulfur or oxygen atom of the P=X group of the monophosphazene structure. Alkylation reactions of N-phosphorylated amides and thioamides take only one course: The formation of products of alkylation at the nitrogen atom is not observed.

In contrast to amides, N-phosphorylthiobenzamides form stable 2:1 lead complexes with chelating trans ligands.Mild oxidation of N-thiophosphorylthioamides forms either disulfides or the corresponding phosphoryl analogs.An x-ray stucture analysis found tha
