Nickel( ii )-mediated cyanamide–pyrazole coupling highlights distinct reactivity of NCNR 2 and NCR nitrile ligands

This is the authors' abstract. We don't add key points for this paper.

The nickel( ii ) center efficiently promotes the cyanamide–pyrazole coupling to give bis-chelate and tris-chelate products. The formation of the tris-chelate product for dialkylcyanamides is thermodynamically favorable.
