Abstract
Reaction of the diprotic ligand [Xanthdim]H (a ligand system where two adjacent β-dialdimine units are linked by a xanthyl backbone) with 2 equiv of potassium hydride or benzylcesium gave access to bimetallic alkali metal complexes. These complexes were structurally characterized by X-ray diffraction, which showed that the β-diiminato units are orientated in a W-conformation. Treatment with 2 equiv of Mg[N(SiMe)] (THF) led to the formation of the heteroleptic complex [Xanthdim][MgN(SiMe)(THF)], that crystallized as a highly strained monomer. The heteroleptic Mg complex is remarkably stable against ligand exchange but is not active in CO /cyclohexene oxide copolymerization. Reaction with Ca[N(SiMe )](THF) gave the homoleptic complex [Xanthdim][Ca(THF)]. Both alkaline-earth metal complexes display considerable distortions in their solid state structure. © 2009 American Chemical Society.
