| titleOfInvention | PROCEDURE FOR THE PREPARATION OF PHOSPHONOSIPYROBISPHENOLS. |
| abstract | Procedure for the preparation of phosphonospirobisphenols, of the general formulas I and II **(See formula)** where R stands for halogen, methyl or ethyl, while R'and R''signify hydrogen, halogen, methyl or ethyl, characterized by reacting a benzylphosphonic acid or one of its compounds of formula Ia **(See formula)** and, respectively, a benzooxaphospholane of formula IIa **(See formula)** where X means the hydroxy group, halogen or an alkoxy group with 1 to 4 carbon atoms, at temperatures between ambient and 350ºC and in a polar solvent, with pentaerythrite or its tetrahalogenated derivative, in the molar ratio of 2: 1.
