Synthesis of New Benzylic Di-, Tri-, and Tetraphosphonic Acids as Potential Chelating Agents
摘要:
New di-, tri-, and tetraphosphonic acids were synthesized starting from four ohydroxymethyl phenol derivatives and obtained in three steps in good overall yield. The phosphonic acids were isolated and purified using semi-preparative C-18 HPLC column. The new compounds were characterized using different spectroscopic methods (H-1, C-13, and P-31 NMR; ESI MS; and MSn, IR).
