The palladium-catalysed direct arylation of pyrazoles with aryl halides, using PdCl(C3H5)(dppb)/KOAc catalyst, reveals a similar reactivity of C4 and C5 CH bonds of pyrazoles, whereas the C3 CH bond is almost unreactive, and gives ac

Pyrazoles are important azole heteroarenes frequently found in pharmaceuticals and protein ligands, and there has been a growing interest in newsynthetic methods for their preparation. We report the first catalytic intermolecular C-H arylation of pyrazole
