Abstract
Pyrazolyl-containing aryliodolium salts undergo transformation to iodopyrazoles accompanied by the formation of a new Csp2–Csp2 bond in the presence of a base (DIPEA, NaOH, or K2CO3). The plausible mechanism of the base-mediated reaction is suggested. The catalytic activity of the iodine-containing species is studied in the model reaction.
