| Abstract: | AbstractA new approach to the synthesis of spirophosphoranes 9, 11, 15a-c containing P-C, P-O, and P-N intramolecular bonds was developed. It is based on the reaction of trivalent phosphorus acid amides with bis(o-hydroxyaryl)diimines. The composition and structure of the products obtained were confirmed by NMR methods, IR spectroscopy, elemental analysis and X-ray analysis. |
