Add time:07/14/2019    Source:sciencedirect.com

By reaction of Li2[PdCl4] with substituted hydrazones of 1H-indole-3-carboxaldehyde the corresponding cyclopalladated complexes have been isolated and characterized. Compound 1a [C11H10ClN3OPd] reacts with PPh3 by halogen displacement giving the cationic complex 5 the X-ray structure of which has revealed metallation at position 4 of the indole hydrazone, which is terdentate forming a [5,6]-fused ring system.
