Abstract:

Neutral palladium(II) and platinum(II) chloro-complexes with the conjugate base of [(pyrrol-2-yl)methylene]quinolin-8-amine were prepared in a single step by reacting 8-aminoquinoline and pyrrole-2-aldehyde with [MCl(CH₃)(COD)] (M = Pd, Pt; COD = 1,5-cyclooctadiene). The reaction consists of a metal-assisted condensation and the protonolysis of the M–C bond by the pyrrole NH. The solid-state structure of the palladium derivative was determined by X-ray diffraction, while the electronic features of the complexes were investigated by means of DFT calculations.

Keywords: Palladium(II); Platinum(II); N-donor ligands; Metal-assisted synthesis
