It was shown that the basicity of the [PhP.sub.1](pyrr) family is less sensitive toward substitution on the aromatic ring than the basicity of analogously substituted anilines.
These measurements give a continuous basicity scale [14, 15] in THF ranging from 2.6 (2-MeO-pyridine ) to 26.6 (2-Cl-[C.sub.6][H.sub.4][P.sub.4](pyrr) phosphazene) in the [pK.sub.[alpha]] units--that is for 24 orders of magnitude.
Self-consistent basicity scale in THF solution ranging from 2-methoxypyridine to EtP1(pyrr) phosphazene.
