Article abstract of DOI:10.1055/s-1997-1230

A general method for the palladium(0)-catalyzed preparation of 4- arylpyrazoles 2, by coupling of either 4-halopyrazoles 3 with arylstannanes 4 or 4-tributylstannyl-1-tritylpyrazole 5 with aryl iodides 6, is reported. Deprotection of trityl and/or methyl
