Abstract:
The kinetics and mechanistic investigation of the reaction between dimethyl acetylendicarboxcylate (DMAD) and Meldrum’s acid has been studied in ethanol environment with triphenylarsine as a catalyst using UV/vis spectrophotometry. The reaction followed second order kinetics. In the kinetics study, activation energy and parameters (Ea, ΔHǂ, ΔSǂ and ΔGǂ) were determined. Also, reaction rate is accelerated by increasing the temperature and the dielectric constant of solvent
