PHOSPHORYLMETHYLPYRIDINES AND THEIR n-OXIDES: SYNTHESIS AND EQUILIBRIUM CH-ACIDITY

Bodrin, G. V.,Matveeva, A. G.,Terekhova, M. I.,Matrosov, E. I.,Petrov, E. S.,et al.

, p. 810 - 818 (2007/10/02)

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 ?C- values.
