The Indirect Study of Rates of Proton-Transfer

  • R. P. Bell

Abstract

We have so far paid no attention to any processes which may occur after a proton has been transferred from an acid to a base, with the production of two new species. These new species may have electron distributions differing considerably from those of the original acid and base, and may therefore undergo further reactions such as decomposition, rearrangement, reaction with the solvent, or with some other species present in solution. It is frequently the case that in the reaction A1 + B2 → B1 + A2 one product (say B1) does undergo further reaction to a product X while the other (A2) does not, so that B2 can easily be regenerated. Under these circumstances we speak of acid-base catalysis, and the reaction just given would be described as the conversion of the substrate Al into X, catalysed by the base B2. Reactions catalysed by acids or bases are of course very common, especially in organic chemistry, and a few examples will be discussed in detail in the next chapter. In the present chapter we shall be concerned with the general kinetic consequences of such behaviour, and in particular how the rates of proton-transfer reactions can be inferred indirectly from studies of acid-base catalysis and related observations. It will then be possible in subsequent chapters to discuss the interpretation of these rates, using information obtained by both direct and indirect methods.
