Abstract

This manuscript reports a novel method for the direct iodination of the C‐4 pyrazole ring generated in situ by the reaction of 1,1,3,3‐tetramethoxypropane and various hydrazines. In this approach, potassium iodate (KIO3) is used as the iodinating agent and (PhSe)2 is used as catalysts under acidic conditions. This protocol provides a convenient method for the efficient synthesis of 4‐iodo‐1‐aryl‐1H‐pyrazoles, valuable intermediates for several different coupling reactions.
