Syntheses, Characterization, and Catalytic Ability in Alkane Oxygenation of Chloro(dimethyl sulfoxide)ruthenium(II) Complexes with Tris(2-pyridylmethyl)amine and Its Derivatives1,2

“…Molecular Structures of Complexes 4, 5, and 8. A single crystal of 4 was obtained as a salt with the [RuCl 3 (Me 2 S O) 3 ] anion unintentionally by the slow diffusion of ethyl acetate to a solution of the crude mixture of 2 and 3 in methanol , An ORTEP drawing of the cation is shown in Figure , and selected bond lengths and angles are listed in Table .…”

“…Pertinent crystallographic data and experimental conditions are summarized in Table . Details of data collection and refinement have been described previously . Selected bond lengths and angles are listed in Table .…”

“…X-ray Structural Analysis of 4. 15 A good single crystal of 4 was obtained as a yellow block (0.20 × 0.10 × 0.08 mm) by the slow diffusion of ethyl acetate to a solution of complex 1 in methanol. Pertinent crystallographic data and experimental conditions are summarized in Table 1.…”

“…Details of data collection and refinement have been described previously. 15 Selected bond lengths and angles are listed in Table 2.…”

“…In this paper, we report the syntheses, characterization, and application to catalytic alkane oxygenation of the ruthenium complexes with a tripodal tetradentate ligand: TPA, 5-(MeOCO) 3 -TPA, TQA, and BPG. The molecular structures of trans (Cl,N amino )-[RuCl(TPA)(Me 2 S O)][RuCl 3 (Me 2 S O) 3 ], cis (Cl,N amino )-[RuCl(TPA)(Me 2 S O)]PF 6 · 1 / 2 MeCN, and trans (Cl,N amino )-[RuCl{5-(MeOCO) 3 -TPA}(Me 2 S O)]PF 6 ·0.2H 2 O complexes have been determined. The bulky 6-position substituents may hinder access of the substrate and/or oxidant to the metal center, while the 5-position substituent has little steric hindrance and is expected to show only an electronic effect.…”
