Abstract
Kinetic evidence is given for Hilgetag's mechanistic conception of the thiono-thiolo isomerization of O,O-dimethyl and O-methyl thionophosphates in acetonitrile solutions containing tetramethylammonium salts with anions derived from the corresponding thionophosphates by demethylation. Some kinetic effects of reactant structures, solvents, and trimethylammonium cation of a salt are mentioned.
