Abstract

Generalization of data on the reaction rate of catalyzed process between mercaptans and phenyl isocyanate in various media led to the conclusion that the reaction rate increased due to the specific, especially nucleophilic, solvation. The primary reaction stage is the formation of a complex between the acidic mercaptan and a base, a catalyst (triethylamine) or basic solvent.
