## Abstract The reactivity of the lithium halides in 83.3% pyridineβdimethylformamide changes from Cl^β^ > Br^β^ > I^β^ to Br^β^ > I^β^ to Br^β^ > I^β^ > Cl^β^ with increasing concentration of the salt from 0 to 0.35 M. This behaviour is explained by ion pairing which reduces the concentration of r

The ways in which nucleophiles may react with cation radicals have recently been discussed in terms of the Dewar-Zimmerman rules. 3-6 A nucleophile which adds either slowly or not at all to a cation radical is thought to be forbidden by symmetry properties from undergoing bond-forming orbital over
The rate constants for the reactions of 4-halomethyl-3-nitrobenzoic acids, the nonnitro derivatives, and their ethyl esters with arylthiolates were measured at different temperatures. It was found that the retardation in rate constants compared to benzyl halides is due to the electrostatic repulsion
