  Phosphorylmethylpyridines and their N-oxides: Synthesis and equilibrium CH-acidity

  摘要：

  Certain phosphorylmethylpyridines and their N-oxides were synthesized, which are of interest as extractants and complex-forming agents. Their equilibrium CH-acidity with reference to 9-phenylfluorene (K+ counterion) was studied by the indicator method in dimethyl sulfoxide. The acidifying action of a series of pyridine groupings was characterized by means of sigma-C- values.
