Abstract
Conductometry in anhydrous hexane at 25 degrees C was used to measure the s tability constants of alkali cation complexes of a series of N,N-diethylcar bamoylmethylphosphine oxides and methylenediphosphine dioxides. The ''anoma lous aryl enhancement'' effect is the strongest in the complexes with tetra phenyldiphosphine dioxide.
