Kinetics of the reaction of 1-tosyl-3-methyl-imidazolium chloride with various amines were measured to examine the nature of sulfonyl transfer in enzymatic reactions.The activations parameters and the value of the Broensted exponent, β=0.48, are consistent with a small degree of bonding between the entering amine and the sulfur atom in the transition state.Similarities in the nucleophilic behavior of sulfonyl and carbonyl groups are detected.
