## Abstract The rate of the reaction between ethyl tosylate and chloride as well as bromide ion has been measured in hexamethylphosphoric triamide in the presence of several counterions. Rate constants for the free ions at 25.0ยฐ are 14.4 mole^โ1^ for chloride and 2.0 mole^โ1^min^โ1^ for bromide, bo
