| Abstract: | Microwave irradiation
has been successfully utilized for the first time for the activation of
unmodified hydrotalcites (HTs, a basic anionic clay), in the Michael addition
reaction between enones and active methylenic compounds under solventless
conditions. In comparison with conventional
heating, microwave process offers an useful alternative for activation of HTs
resulting in reduction of reaction time, better yield and an easy-to-perform
procedure. A plausible mechanism for the observed catalysis is presented. |
