| Abstract: | Abstract Some dicarhoxyphenylphosphonic acids (DCPPA) were prepared by new process. We succeeded in introducing two carhoxyl groups into the phenyl group of phenylphosphonic acid. The dialkyl iso- and tere-phthalate (DACB) were conveniently hrominated with NBS /H2SO4 system to provide the corresponding hromidcs (DACBB) in good yields and good selectivities. |
