3-Iodoindazole allows combined N1- and C3-arylations with boronic acids. These two reactions work independently of one another and can be combined in a one pot procedure. (C) 2000 Elsevier Science Ltd.

CuI-catalyzed coupling of N-acyl-N′-substituted hydrazines with aryl iodides takes place at 60-90 °C to afford N-acyl-N′,N′- disubstituted hydrazines regioselectively and thereby gives a facile method for assembling N,N-diaryl hydrazines. N-Acyl-N′-substituted hydrazines can also react with 2-bromoarylcarbonylic compounds at 60-125 °C under the catalysis of CuI/4-hydroxy-l-proline to provide 1-aryl-1H-indazoles.
