The title compound, [Ru(C7F5O2)2(C10H14)(C21H24N2)]·2CH2Cl2, is formed as an orange crystalline powder by the reaction of RuCl2(p-cymene)(IMes) and AgOCOC6F5 in anhydrous tetra-hydro-furan (IMes = 1,3-dimesityl-2,3-di-hydro-1H-imidazol-2-yl-idene). The asymetric unit consists of two independent [Ru(C6F5COO)2(η(6)-p-cymene)(IMes)] com-plexes and four dichloro-methane solvent mol-ecules. In each ...

The light-protected reaction of [(eta(6)-p-cymene)Ru(II)Cl(2)](2) with 1-(2-hydroxyethyl)piperazine in dry methanol, followed by addition of excess NH(4)PF(6), afforded the complex [(eta(6)-p-cymene)Ru(II)(NH(3))(2)Cl](PF(6)) () in 47% yield. Attempts to use the same protocol for the synthesis of [(eta(6)-p-cymene)Os(II)(NH(3))(2)Cl](PF(6)) led to the isolation of the binuclear triply methoxido...

We report our third and final investigation into the use of ruthenium based compounds for catalyzing the hydrosilylation of methylvinyldimethoxysilane with methyldimethoxysilane. The catalytic mechanism of dichloro(p-cymene)ruthenium(II) (B1) is examined and compared to that of previously studied, less active catalysts. Density functional theory (DFT) has been applied to explore the possibility...

Two new p-cymene based diphenols (1-2) were isolated from the heartwood of Calocedrus decurrans. Structures were elucidated by 1D and 2D NMR techniques and HRMS. Libocedroquinone (3) was also isolated as a natural product for the first time. A new system of nomenclature is proposed for description of such oligomeric p-cymene derivatives.

Four novel ruthenium organometallic complexes: [(η⁶-p-cymene)Ru(4,4,4-trifluoro-1-(4-bromophenyl)-1,3-butanedione)Cl] (1), [(η⁶-p-cymene)Ru(4,4,4-trifluoro-1-(4-bromophenyl)-1,3-butanedione)pta]PF₆ (2), [(η⁶-p-cymene)Ru(4,4,4-trifluoro-1-(4-iodophenyl)-1,3-butanedione)Cl] (3) and [(η⁶-p-cymene)Ru(4,4,4-trifluoro-1-(4-iodophenyl)-1,3-butanedione)pta]PF₆ (4) were synthesized and characterized by ...

On questioning 126 households, only 9 (7.1 percent) used iodized salt whilst 74 (58.7 percent) households used only uniodized coarse salt and 7 (5.6 percent) used only uniodized fine salt. The remaining 36 (28.6 percent) households used both fine and coarse uniodized salt. Undoubtedly at this point in time legislation on "table" salt iodization must be interpreted to mean not only the iodizatio...

achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...
