High-pressure kinetics of the reaction of p-benzoquinone with di-n-butylamine in some aprotic solvents

Abstract

The kinetics and the volume of activation of the title reaction to form 2-dibutylamino-p-benzoquinone in 1,2-dicholoroethane and acetonitrile, –54 ± 2 and –67 ± 2 cm³/mol respectively, strongly support a reaction scheme in which ionic species are formed prior to the rate-determining step which is the second attack by the amine.
