## Abstract We report a study on the quaternization and dequaternization of pyrazoles by conventional heating and microwave irradiation in solvent‐free conditions. Microwave irradiation produces an acceleration in the quaternization rate and a rapid equilibration between quaternized and non quatern

## Abstract The use of sodium hydrogen carbonate under solvent‐free conditions and microwave irradiation is by far the best method for __N‐__alkylating pyrazoles. The yields are good and the method is devoid of side reactions (quaternization, isomerization, hydrogen halide elimination). Solvent‐fre
