Kinetics of deuterium isotope exchange between thiophenol or t-butylthiol and i-propylthiol

  • A. Wawer

The rate constants and activation energies of bimolecular deuterium exchange in the systems: C5H5SD+i-C3H7SH and t-C4H9SD+i-C3H7SH in dilute C6H12 solutions have been established. The concerted H-transfer inside the cyclic dimer with two H-bonds formed in these systems is probably the rate-limiting step. The rate constant for H-transfer inside the cyclic dimer is independent of the acidic properties of the thiols.

Определены константы скорости и энергии активасии бимолекулярного дейтерийного обмена в системах: C6H5SD+i-C3H7SH и трет-C4H9SD+i-C3H7SH в разбавленных раствораш C6H12. Согласованный перенос водорода внутри димера с двумя Н-связями, образующимися в этих системах, вероятно является ступенью, лимитирующей скорость. Константа скорости переноса водрода внутри циклического димера не зависит от кислотных свойств тиолов.
