α-SUBSTITUIERTE PHOSPHONATE 55. EIN NEUES TRIPHOSPHONAT AUS BISPHOSPHONO-CHINONMETHID UND DIALKYLPHOSPHIT

By oxidation of 3,5-di-tert-butyl-4-hydroxyphenylmethanephosphonate (4) or the analogous arylsubstituted bisphosphonate (5) with PbO2 the hitherto unknown 7-mono- or 7.7-bisphosphonylated quinonemethides (13) or (11), resp., are formed in good yields.The quinonemethides simply added dialkylphosphite to form the bisphosphonate (5) or the trisphosphonate (13), the latter having a remarkable stability.The structures of the quinonemethides (13) and (11) as well as of the tris-phosphonate (12) could be proved unambiguously by IR-, 1H-, 13C- and 31P-NMR spectra.
