been prepared and converted into five-co-ordinatephosphoranes by addition of 4,5-dimethyl-o-benzoquinone or 4,4′-dimethylbenzil, or condensation with 4,5-dimethylpyrocatechol or pinacol. The variable-temperature n.m.r. spectra of these phosphoranes are discussed. In these systems phenylamino- and dimethylamino-groups have similar apicophilicities and are less apicophilic than hydrogen by some 4–5 kcal
