Abstract:

In recent years, the chemistry of organotin and organogermanium compounds was extensively studied due to their biological ativity. In our early work, the organotin carboxylate, dithiopiperdylcarboxylate and alkynyl phophate were synthesized. Their structure and biological activity were studied also. Up to now, the organgermanium carboxylate were reported very little, but bis(triorganogermanium) dicarboxylate have not been reported. In this work, bis(triphenylgermanium) dicarboxylates were synthesizd by triphenylgermanium chloride with dicarboxylates in 2:1 molar ratio. Their structure were characterized by elemental analysis, IR, ¹H NMR and MS.It is showed that the carboxylate group act in a monodentate fashsion similar to that found for the tin analgue.
