摘要

Upon UV-irradiation, the C–P bond of (4-pyridylmethyl) phosphonic acid cleaved only near the isoelectronic point to give 4-methylpyridinium phosphate, while (1-benzyl-4- pyridiniomethyl) phosphonic acid underwent C–P bond cleavage above pH 4 to give 1- benzyl-4-methylpyridinium phosphate. On the other hand, the C–P bond of (2-pyridylmethyl) phosphonic acid cleaved under pH region of about 1 to 2, while (1-benzyl-2- ...
