Coordination Studies of a Triazole‐Substituted 3H‐1,2,4‐Diazaphosphole: CC and CN Bond Activation Induced by Cobalt(0) and Nickel(0) Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Reactions of a triazole‐substituted 3H‐1,2,4‐diazaphosphole with electron‐rich cobalt and nickel complexes result in the selective cleavage of CC and CN bonds on the triazole, forming chelate complexes with the activated diazaphosphole ligand. The reactivity of the recently reported 3H‐1,2,4‐diazaphosphole 1 toward electron‐rich Ni and Co complexes ...
