In base-catalyzed oxidation of a pair of associating thiols [HSCH2–CONHCONH–R1 and HSCH2CH2–NHCONHCO–R2] (R1=n-C4H9, R2=n-CnH2n+1) with oxygen, the selectivity (a measure of molecular recognition) at 35.0°C reached a maximum for R1=R2 (=n-C4H9) both in aqueous acetonitrile (n=2 to 6) and in aqueous ethanol (n=3 to 5).

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。
