Several new arene-phosphine ligands were synthesized and used to prepare the following series of tethered dialkylruthenium(II) complexes: (eta(6):eta(1)-C6H5CH2CH2PR2)Ru(CH3)(2), where R = Cy (1), Ph (2), Et (3). The structures of complexes 1 and 2 were determined by X-ray diffraction. While complexes 1 and 2 were found to be more thermally stable than analogous nontethered analogues, complex 3 was found to decompose at room temperature. In preliminary studies, the use of complexes 1 and 2 as catalyst precursors for the polymerization of ethylene was examined.
