Commercially available polyphenols react with diethylphosphite to give polyphosphonates, which are easily transformed by LDA in good yields to polyorthohydroxy aryl phosphonates. Moreover, some bis-benzyl aminobenzyl phosphonates have been prepared in good yields. These new monomers are of great relevance for the synthesis of thermal resistant polycondensates containing phosphonate moieties.
