Abstract
Abstract The MPV reaction of several substituted acetophenones with 2-propanol over an Mg(Al)O x catalyst were carried out to estimate the Hammett’s reaction constant. Also, the MPV reaction of acetophenone was carried out at different temperatures and variable amount of catalyst and 2-propanol:acetophenone molar ratios. The results show that the optimal reaction conditions are: 82 °C, 1 g of catalyst and an alcohol:ketone molar ratio of 30. In these conditions the yield and selectivity to 1-phenylethanol are 90% and 100%, respectively. These results are similar or better than the obtained by other catalysts in this process.
