Four ruthenium(II) complexes 1—4 [RN=CH‐(2,4‐( t Bu) 2 C 6 H O)]RuH(PPh 3 ) (CO) (R = 5 , 1; R 4‐MeC 4 2; 4‐ClC 3; 4‐BrC 4) bearing Schiff base ligands were prepared by treating RuHClCO(PPh with RN=CH‐(2,4‐( OH (L1—L4) in the presence of triethylamine. Their structures fully characterized elemental analysis, IR, NMR spectroscopy and X‐ray crystallography. These Ru(II) exhibit high catalytic performance good functional‐group compatibility acceptorless dehydrogenation secondary alcohols,...
An efficient method for direct oxygenation of primary arylamines to nitriles and amides with switchable selectivity was developed using N,O-bidentate Ru<sub>3</sub> clusters as catalysts.
Reactions of substituted pyridylalkanol 6‐CH 3 PyCH 2 CH(OH)R (R = Ph (L 1 H), R 4‐CH C 6 H 4 4‐OCH 4‐ClC 4‐BrC 5 4‐CF H)) with Ru (CO) 12 in refluxing tetrahydrofuran afforded the corresponding ruthenium carbonyl complexes [6‐CH CHRO] 8 ( 1a ), 1b 1c 1d 1e 1f )) good yields. These were well characterized using elemental analysis and Fourier transform infrared NMR spectroscopies. Furthermore, their crystal structures determined single‐crystal X‐ray diffraction analysis. Complexes – found to...
Abstract Treatment of Ru 3 (CO) 12 with one equivalent 2‐indolyl‐6‐pyridinyl‐alcohol ligands 2‐(C 8 H 6 N)‐6‐(CR 1 R 2 OH)C 5 N (R = Me ( L1H ); C L2H , −(CH ) 4 ‐ L3H );& L4H )) in refluxing THF afforded the corresponding trinuclear ruthenium clusters L(μ ‐H)Ru 9 1a – 1d ), respectively. All novel complexes were well characterized by NMR, elemental analyses and IR spectra. Structures 1c further determined X‐ray crystallographic studies. Complexes applied to catalytic Oppenauer‐type...
Eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) are important ω -3 polyunsaturated fatty acids. Their physiological effects on humans not exactly the same; therefore, production of products with high-purity EPA or DHA monomers is significant. In this work, ethyl ester (EPA-EE) (DHA-EE) were first separated using HPLC poly(styrene-co-divinylbenzene) (PS/DVB) as stationary phase. The mobile phase, PS/DVB particle diameter, column temperature systematically evaluated. results showed that...
