REARRANGEMENT OF DI-T-BUTYL ARYL PHOSPHATES TO DI-T-BUTYL(2-HYDROXYARYL)PHOSPHONATES. PREPARATION OF (2-HYDROXY-1,3-PHENYLENE)BISPHOSPHONIC ACIDS

Di-t-butyl aryl phosphates 3 on treatment with lithium diisopropylamide rearrange to di-t-butyl (2-hydroxyaryl)phosphonates 5.A di-t-butyl (2-hydroxyaryl) phosphonate on reaction with di-t-butyl phosphorochloridate yields a phosphate-phosphonate 8 which o

o-Hydroxyaryl Diphosphonic Acids

Treatment of dialkyl aryl phosphates with n-butyllithium or lithium diisopropylamide results in a rearrangement that involves the fission of an oxygen-phosphorus bond and formation of a C-P bond yielding dialkyl (2-hydroxyaryl)phosphonates.A dialkyl (2-hy
