Abstract:

Palladacycles are an important class of organometallic compounds. They are interesting for their stability and for their important applications as catalysts in cross-coupling reactions. The work described herein relates to the synthesis of a dicyclometallated compound stemming from a diimine ligand, with a doubly metallated aromatic ring. Its reactivity towards a variety of tertiary diphosphines is also considered. The latter ligands show diverse coordination modes, opening the possibility of synthesizing quite different and complex structures bearing transition metal atoms in close proximity to each other.

Keywords: Palladium; cyclometalation; diimine; polymetallic complexes
