Phosphoranides

WebPhosphoranides A are hypervalent anionic phosphorus (III) compounds formally possessing a 10-electron valence shell and a distorted pseudotrigonal bipyramidal arrangement at the phosphorus atom. The electronegative ligands at phosphines make nucleophilic addition possible to afford stable phosphoranides (Figure 1 ). Figure 1 WebThe relative alkylating activities of two of the cytotoxic metabolites of cyclophosphamide, phosphoramide mustard and nornitrogen mustard, have been studied at pH 4.6 and 7.4. The products formed on alkylation of ethanethiol by these metabolites have
