SYNTHESIS OF ACID-LABILE GEMINAL BIS- AND TRIPHOSPHONIC ACIDS

Sodium salts (7,8 respectively) of the unsaturated bisphosphonic acids 5 (2,6-di-tert-butyl-7,7-bis(phosphono)-1,4-benzoquinone-4-methide) and the trisphosphonic acid 6 (4-hydroxy-3,5-di-tert-butylphenylmethane tris(phosphonic acid), were prepared by buffered hydrolysis of the corresponding trimethylsilyl esters.The structures of 7 and 8 were determined by 13C and 31P NMR analysis.Compound 8 is the first wellestablished example of a gem trisphosphnic acid salt. Key words: 7-phosphono-quinonemethide salts; arylmethane trisphosphonate; bromotrimethylsilane; silyldealkylation; 13C, 23Na, 31P NMR data.
