| titleOfInvention | PROCESS FOR PREPARING SUBSTITUTED 1-HYDROXY-1,1-DIPHOSPHONESAES AND THEIR DERIVATIVES |
| abstract | The invention relates to a process for the preparation of novel substituted 1-hydroxy-1,1-diphosphonigsÄuren and their derivatives of the general formulas I and II by reacting bis-trimethylsilyl hypophosphite with carboxylic acid chlorides and hexamethyldisilazane in the approximate molar ratio of 2: 1: 0.33 under a protective gas atmosphere to compounds of the formula I, which are converted by solvolysis in the presence of bases into compounds of the formula II. The compounds are suitable as complexing agents in corrosion inhibitors and galvanic baths. Formulas I and II |
