Abstract

Rates of formation of electron donor–electron acceptor complexes of iodine with some compounds of the general formula R2CS with iodine (R2CS⋯ I—I) in 1-chlorobutane have been determined by means of a microwave temperature-jump apparatus. For each of these reactions, the observed forward rate constant (kf) is proportional to the theoretical diffusion- controlled value (k* D) over a range of temperatures, but somewhat smaller. The values of ...
