| Abstract: | Reactions of 5,7-dichloro-4,6-dinitrobenzofuroxane and 5,7-dichloro-4,6-dinitrobenzofurazane with triphenylphosphine proceed through a nucleophilic aromatic substitution of chlorine and nitro groups in the sixmembered ring of the heterocycles. The structure of the phosphorylation products was established from the IR, 31P NMR, and mass spectra and from XRD and elemental analysis. Schemes of the routes of the phosphorylation are discussed. |
