摘要

A kinetic and thermodynamic study of the reaction of the 2, 4, 6-triphenylthiopyrylium ion (1) with butylamine and cyclohexylamine has been performed in MezSO at 25" C. The reaction involves the initial formation of both the corresponding 2H-and 4H-thiopyrans, which equilibrate to form only the more stable 2H adduct. The kinetic data are consistent with a two- step process wherein the formation of the protonated 2H-and 4H-thiopyran intermediates ...
