Preparation and crystal structure of metallated 2,4,6-trimethylaniline imines

Abstract

In a typical condensation reaction, Schiff Base ligands were synthetized from 2,4,6trimethylaniline and the appropriate aldehydes. Treatment of the ligands with the corresponding palladium salt provided dinuclear cyclometallated compounds with bridging acetate moieties. The X-ray crystal structure analysis carried out was in agreement with the spectroscopic data. Herein we describe the preparation of the complexes; a brief discussion of the crystal structure is also given. The resulting dinuclear palladacycles are suitable for further ligand-exchange processes.
