Abstract
The cycloaddition reaction between 2,3-dimethylbuta-
1,3-diene and methylacrylate proceeds by the second order
kinetics. The rate constants increase with the increase in the
excess of one of the reactants. The change in the effective rate
constants is described by the Michaelis–Menten equation
indicating that the reaction proceeds through the initial
equilibrium stage of formation of an intermediate complex which
then transforms into the product. The effective rate constants, the
equilibrium constants of formation of the intermediate complex,
and the rate constant of its transformation into the reaction
product were determined, as well as the thermodynamic
parameters of the formation of the intermediate complex and the
activation parameters of the transformation of the intermediate
complex into the product. The limiting stage of the reaction is
established and itsmechanism is suggested.
