Hydrazone formation is strongly accelerated in the presence of both zinc ions and an auxiliary amine, traced to the very fast initial formation of the reactive Zn II ‐imine complex presenting a C=N bond metallo‐activated towards reaction with the hydrazine component. The synergistic effect combining metallo‐ and organo‐catalysis points to a powerful co‐catalysis strategy of bond formation in DCC through interconnected chemical transformations.
