Abstract: The complexes TpRu[P(OCH₂)₂(OCCH₃]-(PPh₃)Cl (2) [Tp = hydridotris(pyrazolyl)borate; P- (OCH₂)₂(OCCH₃) (1) = (4-methyl-2,6,7-trioxa-1-phosphabicyclo[2,2,1]heptane] and TpRu(L)(PPh₃) CL [L = P(OCH₂)₃CEt (3), PMe₃ (4) or P(OMe)₃ (5)], (η⁶-C₆H₆)Ru(L)Cl₂ {L = PPh₃ (6), P(OMe)₃ (7), PMe₃ (8), P(OCH₂)₃CEt (9), CO (10) or P(OCH₂)₂(OCCH₃) (11)] and (η⁶-p-cymene)Ru(L)Cl₂ [L = P(OCH₂)₃CEt (12), P(OCH₂)₂(OCCH₃)P(OCH₂)₂(OCCH₃) (13), P(OMe)₃ (14) or PPh₃ (15)] have been synthesized, isolated, and characterized by NMR spectroscopy, cyclic voltammetry, mass spectrometry, and, for some complexes, single crystal X-ray diffraction. Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorous-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru (II) complexes show that P(OCH₂)₂(OCCH₃) has a cone angle of 104. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH₂)₂(OCCH₃) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorous ligands; however, the Ru(III/II) potential for (η⁶-C₆H₆)Ru(CO)Cl₂. For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of I being less than other common phosphines (e.g., PMe₃ or PPh₃) or phosphites [e.g., P(OCH₂)₃CEt or P(OMe)₃] but greater than carbon monoxide.
