Abstract
Nine diaryldithiocarbamates have been prepared. Kinetic study of their hydrolysis has revealed that this hydrolysis proceeds by E1cB mechanism in the pH range 2 to 12. Values of activation entropies, reaction constants, Broensted coefficient, and comparison with reactivity of the corresponding N-methyl analogue have been used as criteria for the suggested mechanism. In acid media pH 2 to 0.4 and H0 -0.6 the hydrolysis follows a mechanism analogous to AAc2. Results of hydrolyses of dithiocarbamates, thiocarbamates and carbamates are compared.
