Reactivity of Mannich bases. Part X. The mechanism of the reaction between β-amino-ketones and thiophenols
Abstract
The replacement of the alkylamino-group by a phenylthio-group in some Mannich bases was studied. The effects on the reaction kinetics of variation in the pH, of the substituents, and of various thiophenol reagents, and some studies with optically active compounds, indicate that the reaction proceeds through an elimination–addition mechanism.
