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 recognitionbetween (1) and (2)] for R (i.e.,n-C6H13-C6H13 >cyclo-C6H11) depends upon the strength of the phenyl–R interactions.
在氧化各自具有苯基或己基的一对缔合硫醇[(1)和(2)]时(R = nC 6 H 13,iC 6 H 13,环C 6 H 11)。表明,选择性的顺序[(间的识别的程度的量度1)和(2)]为R(即,NC 6 H ^ 13 - c ^ 6 ħ 13 >环-C 6 H ^ 11)取决于苯基-R相互作用的强度。

A new parameter (S1) representing the three-dimensional shape similarity between groups is defined as the degree of a maximal overlap between a pair of groups located within a three-dimensional grid. S1, which ranges from 0 to 1, has been calculated for 105 pairs of groups including straight-chain (C1-C6), branched (C4-C6), and cyclic alkyl groups, and a phenyl group. A close relationship has been found to exist between S1 and (i) the degree of the discrimination between groups by a given group in the oxidation of a pair of associating thiols and (ii) relative biological activity (i.e., effect on cat blood pressure) of a homologous series of benzilic esters.
