Control of the degree of molecular recognition by shape-specific weak interactions between nonpolar groups
Abstract
In oxidation of a pair of associating thiols [(1) and (2)], each having a phenyl or a hexyl group (R = n-C6H13, i-C6H13, cyclo-C6H11), it has been shown that the order of the selectivity [a measure of the degree of the recognition between (1) and (2)] for R (i.e.,n-C6H13-C6H13 >cyclo-C6H11) depends upon the strength of the phenyl–R interactions.
