Abstract
Rate constants for the reactions of Laser flash photolytically generated benzhydrylium ions (diarylcarbenium ions) with halide ions have been determined in various solvents, including neat and aqueous acetonitrile as well as some alcohols. Substitution of the rate constants into the correlation equation log k= s (N+ E) yields the nucleophilicity parameters N for the halide ions in different solvents. Linear correlations with negative slopes are found ...
