Palladium-catalysed direct diarylations of pyrazoles with aryl bromides: A one step access to 4,5-diarylpyrazoles

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

Pd-catalysed direct 5-arylation of 1-methylpyrazole with aryl bromides

1-Methylpyrazole was found to be a suitable partner for palladium-catalysed direct arylation through C-H activation/functionalisation using aryl bromides. The reaction conditions and the nature of the catalyst were found to have a determining influence on
