Abstract
The structure and intramolecular transformations of the N,N'-bis[diisopropo xy(thio)phosphoryl(thio)carbonyl]-1,10-diaza-18-crown-6 ethers in CCl4, CDC l3, CD2Cl2, (CD3)(2)CO, and CD3CN solutions were studied by H-1, C-13, and P-31 NMR spectroscopy. It was found that the compounds under study are high ly labile in solution and exist as a variety of tautomers and conformers. T he C=O- and P=S-containing derivative was proposed to undergo intermolecula r tautomerization.
