In oxidation of a pair of associating thiols (1d and 2) with O2, specific weak interactions related to their geometrical shape such as CH...N and CH...SH interactions are suggested to be responsible for selective molecular recognition.

Oxidation of a pair of associating thiols (1 and 2), each having a binding site and a recognition site (R1 or R2), is examined in binary solvent mixtures of a propanol with water and organic co-solvents.The selectivity (r) - a measure of the degree of recognition of (1) by (2) - in the oxidation is represented by the logarithmic ratio of the yield of an unsymmetrical disulphide to twice that of a symmetrical one.It is found that (i) higher selectivity is achieved when the non-polar group of a propanol in a mixed solvent resembles a given non-polar group of one of the reacting molecules in three-dimensional shape and (ii) the above "solvent shape effect" on the selectivity is produced more markedly in aqueous propanols than in the corresponding non-aqueous ones.Correlation of the observed selectivity with physico-chemical properties of (aqueous) propanols, reactivity difference between thiols, and so on is discussed together with a possible explanation of the solvent shape effect on the degree of recognition of non-polar groups.

Based on the selectivity in the oxidation of a pair of thiols (1 and 2) with O2, it is suggested that maximal recognition between 1 and 2 occurs when 1 and 2 are similar in the structure of the binding sites to each other.
