The ligand bis-1-(1′-diphenylphosphinoferrocenyl)phenylphosphine, triphosfer, reacts with dichlorotris-triphenylphosphineruthenium(II) to give the complex [(triphosfer)RuCl2], (17), in almost quantitative yield. This complex reacts with CO at ambient temperature to afford [(triphosfer)Ru(CO)Cl2]. Three related complexes, [{(η-R2PC5H4)Fe-μ2-(η-C5H4P(R′)η-C5H4)Fe(η-C5H4R2)}RuCl2], R,R′=Ph, iPr (18-20), exhibit identical chemical properties. Reaction of complexes 17-20 with excess PMe2Ph results in the deligation of the ferrocene ligand. The electrochemistry shows that while the diferrocenyltriphosphine ligands undergo a single two-electron oxidation, irreversible in character, complexes (17-19) exhibit two separated one-electron oxidations having features of chemical reversibility. This data suggests that while within the ligands no electronic communication exists between the two ferrocene subunits, complexation with RuCl2 allows communication between the two ferrocenes. The single crystal X-ray structure of [(triphosfer)RuCl2] has been determined.
