Synthesis and Structural Characterization of (1,3-Bis(methoxyethyl) Bis(2,4,6-Trimethylphenyl) Rhodium(I)

Abstract

A new N-heterocyclic carbene (NHC) ligand with bulky substituents and functionalized methoxy-donor side arms complexed with Rh(I) was synthesized and characterized by elemental analysis, 1H and 13C NMR, and IR spectroscopy. The crystal and molecular structure was determined by single-crystal X-ray diffraction techniques. Two carbon atoms in the cyclooctadiene ring and three ortho methyl groups have positional and orientational disorder, respectively. Rhodium has square-planar coordination geometry. © 2006 Taylor & Francis.
