Kinetics and mechanism of the aminolysis of aryl N-ethyl thiocarbamates in acetonitrile

The aminolysis of aryl N-ethyl thiocarbamates (EtNHC(=O)SC 6H4Z) with benzylamines (XC6H 4-CN2NH2) in acetonitrile at 30.0 °C is investigated. The rates are faster than the corresponding values for aryl N-phenyl thiocarbamates (PhNHC(=O)SC6H4Z), reflecting a stronger push to expel the leaving group by EtNH than the PhNH nonleaving group in a concerted process. The negative ρXZ (-0.86) and failure of the reactivity-selectivity principle found are consistent with the concerted mechanism. The kinetic isotope effects involving deuterated nucleophiles (k H/kD = 1-5-1.7) and low ΔH? with large negative ΔS? values suggest a hydrogen bond cyclic transition state.
