ChemInform Abstract: Copper(I)/Copper(II)‐Assisted Tandem Catalysis: The Case Study of Ullmann/Chan—Evans—Lam N 1 ,N 3 ‐Diarylation of 3‐Aminopyrazole

Regioselective Cu‐catalyzed Ullmann‐type N‐arylation of 3‐aminopyrazoles (I) with aryl iodides and the Chan—Evans‐type coupling of 3‐amino‐1‐aryl‐pyrazole (IIIb) with arylboronic acids proceed with good to excellent yields.
