More Information
Summary:Novel zerovalent arene complexes bearing two dimethyl fumarate ligands, Ru(eta(6)-arene)-(dimethyl fumarate)(2) (arene = benzene (2a), toluene (2b), p-xylene (2c), mesitylene (2d), hexamethylbenzene (2e), tert-butylbenzene (2f), anisole (2g), N,N-dimethylaniline (2h), biphenyl (2i), methyl benzoate (2j), naphthalene (2k)), were synthesized via the direct ligand exchange reaction of Ru(eta(6)-cot)(dimethyl fumarate)(2) (1; cot = 1,3,5-cyclooetatriene) with arenes. The detailed structures of 2g,h were determined by X-ray crystallography, which revealed that the coordination geometry can be represented by a highly distorted trigonal bipyramid.
