data on the energetics of the pseudorotation processes available to these systems. It is concluded that the apicophilicities of phenoxy- and phenylthio-groups are similar, with the balance varying according to the nature of the other ligands. Further evidence is given for the high apicophilicity of the hydrogen atom. The concept of multiple turnstile rotation processes is discussed with particular reference

The synthesis of about forty new spirophosphoranes containing a PH bond offers examples of new cases of tautomeric equilibrium between the triand pentacoordinated forms as shown by: (a) recording the 31P NMR spectra between 20 and 150°, (b) using a chemical test which is specific of the PIII form. These results allowed us to discuss factors influencing the equilibrium PIII ⇌ PV.

Investigation of the reactions of α-azidocarboxylic acids, N-(2-azidoethyl) amides and N-(2-azidoethyl) amines with trivalent P compounds shows that the intramolecular cyclization to spirophosphoranes of the intermediate phosphazo-compounds is typical of the azides of the first and third types but not of the second type. It is concluded that such cyclization is possible only where the functional group

The reaction of pyrocatechol chlorophosphite with N-trimethylsilylacetamide gave 2-acetamido-4,5-benzo-1,3,2-dioxaphospholane. The reaction of this product with hexamethyldisilazane leads to 2-trimethylsiloxy-4,5-benzo-1,3,2-dioxaphospholane, while its reactions with diethylamine, trimethylsilyldiethylamine, and bis(dimethylamino)methane give 2-dialkylamino-4,5-benzo-1,3,2-dioxaphospholanes.
