A kinetic study of Heck reaction of iodobenzene and methyl acrylate using homogeneous Pd/TPP catalyst

摘要

A kientics of Heck vinylation of iodobenzene ith methyl acrylate has been studied using homogeneous Pd(OAc)_2/TPP catalyst in the temperature range of 50-70 deg C. The rate of reaction shows linear dependence with iodobenzene concentration. Teh effect of catalyst and methyl acrylate concentrations shows linear dependence initially and marginally increases afterwards. The effect of triethylamine concentration passes through a maximum. An empirical rate equation has been derived to fit the experimental data, showing accuracy in the range of +-8
