N-heterocyclic compounds have been tested in the selectivehydrogenation catalysed by small 1-3 nm sized Ru nanoparticles (NPs) embedded in various imidazolium based ionicliquids (ILs). Especially a diol-functionalised IL...

generally easily accessible and strongly favored at the α‐position using classical palladium‐catalysis. Conversely, regioselective functionalization of such heterocycles at the concurrent β‐position remains currently very challenging. Herein, we report general conditions for regioselective direct arylation at the β‐position of pyrazoles, while C−H α‐position is free. By using aryl bromides as the aryl

The use of sodium hydrogen carbonate under solvent-freeconditions 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-freeconditions are the only ones that allow us to prepare 1-substituted pyrazoles from secondary halides. The procedure using
