| Abstract: | Abstract Esters of N-Phosphoryl phosphazenes are prepared by a modified Atherton-Todd reaction from di- and triesters of phosphorous acid, sodium azide, and carbon tetrachloride in high yields. The utilization of the two-component system trialkyl phosphite/ carbon tetrachloride for preparing phosphazenes, (RO)3Pdbnd]NY (Y: PO(OR)2, SO2R, COR, CN), and dialkoxyphosphoryl compounds, (RO)2P(O)X (X: NHR, NR2, OPh, CN, F, NCO), is presented. |
