Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 122-99-6, Name is 2-Phenoxyethanol, molecular formula is C8H10O2, belongs to phthalazine compound, is a common compound. In a patnet, author is Cabeza, Javier A., once mentioned the new application about 122-99-6, Name: 2-Phenoxyethanol.
Reactions of phthalazine, quinazoline, 4,7-phenanthroline and 2,3 ‘-bipyridine with ruthenium carbonyl
The reactions of [Ru-3(CO)(12)] with four aromatic diazines have been studied in THF at reflux temperature. With phthalazine (L-1), the compound [Ru-3(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(7)] (1), which contains an intact phthalazine ligand in an axial position bridging an Ru-Ru edge through both N atoms, is initially formed but it reacts with more phthalazine to give [Ru-3(kappa N-2-L-1)(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(6)] (2), in which a pi-pi stacking interaction between the aromatic rings of both ligands determines their position in cluster axial sites on the same face of the Ru3 triangle. With quinazoline (HL2), the cyclometalated hydrido decacarbonyl derivative [Ru-3(mu-H)(mu-kappa(NC4)-N-2-C-3-L-2)(CO)(10)] (3) is initially produced but it partially decarbonylates under the reaction conditions to give [Ru-6(mu-H)(2)(mu-kappa(NC4)-N-2-C-3-L-2)(mu(3)-kappa(3)-(NNC4)-N-1-C-3-L-2)(CO)(19)] (4), which results from the displacement of a CO ligand of 3 by the uncoordinated N-1 atom of another molecule of 3. With 4,7-phenanthroline (H2L3), the stepwise formation of the cyclometalated derivatives [Ru-3(mu-H)(mu-kappa(NC3)-N-2-C-4-HL3)(CO)(10)] (5) and two isomers of [Ru-6(mu-H)(2)(mu(4)-kappa(NCNC8)-N-4-C-4-N-3-C-7-L-3)(CO)(20)] (6a, 6b) takes place. In compounds 6a and 6b, two Ru-3(mu-H)(CO)(10) trinuclear units are symmetrically (C-2 in 6a or C-S in 6b) bridged by a doubly-cyclometalated 4,7-phenanthroline ligand. With 2,3′-bipyridine (HL4), two products have been isolated, [Ru-3(mu-H)(mu-kappa N-2(3)’ C-4′-L-4)(CO)(10)] (7) and [Ru-3(mu-H)-(mu-kappa(NN3)-N-3-N-2’C-2′-L-4)(CO)(9)] (8). While compound 7 contains an N-3′ C-4′-cyclometalated 2,3′-bipyridine, in compound 8 an N-3′ C-2′-cyclometalation is accompanied by the coordination of the N-2 atom of the remaining pyridine fragment. The structures of compounds 2, 3, 4, 6a and 8 have been determined by X-ray diffraction crystallography.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 122-99-6. The above is the message from the blog manager. Name: 2-Phenoxyethanol.
