The lithium and cesium salts of tri(p-anisyl)methane, diphenyl(2-pyridyl)methane, diphenyl(4-pyridyl)methane, and diphenylacetonitrile in dimethoxyethane exist as an equilibrium mixture of ion pairs, predominantly of the contact pair type, and free ions.Relative to the alkylation of these alkaline salts by 1-bromobutane, the reactivity of the carbanions (ki) increases in the series: diphenylcyanomethyl .The reactivity of the carbanions is from one to three orders of magnitude greater than the rectivity of the ion pairs depending on the structure of the carbanion and cation size.
