category: Tetrahydropyrans. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.
The reactions of bidentate diimine ligands (L2) with binuclear [Ru(L1)(CO)Cl2]2 complexes [L1 ? L2 = 2,2?-bipyridine (bpy), 4,4?-dimethyl-2,2? -bipyridine (4,4?-Me2bpy), 5,5?-dimethyl-2,2? -bipyridine (5,5?-Me2bpy), 1,10-phenanthroline (phen), 4,7-dimethyl-1,10-phenanthroline (4,7-Me2phen), 5,6-dimethyl-1,10-phenanthroline (5,6-Me2phen), di(2-pyridyl)ketone (dpk), di(2-pyridyl)amine (dpa)] result in cleavage of the dichloride bridge and the formation of cationic [Ru(L1)(L2)(CO)Cl] + complexes. In addition to spectroscopic characterization, the structures of the [Ru(bpy)(phen)(CO)Cl]+, [Ru(4,4?-Me 2bpy)(5,6-Me2phen)(CO)Cl]+ (as two polymorphs), [Ru(4,4?-Me2bpy)(4,7-Me2phen)(CO)Cl]+, [Ru(bpy)(dpa)(CO)Cl]+, [Ru(5,5?-Me 2bpy)(dpa)(CO)Cl]+, [Ru(bpy)(dpk)(CO)Cl]+, and [Ru(4,4?-Me2bpy)(dpk)(CO)Cl]+ cations were confirmed by single crystal X-ray diffraction studies. In each case, the structurally characterized complex had the carbonyl ligand trans to a nitrogen from the incoming diimine ligand, these complexes corresponding to the main isomers isolated from the reaction mixtures. The synthesis of [Ru(4,4?-Me2bpy)(5,6-Me2bpy)(CO)(NO 3)]+ from [Ru(4,4?-Me2bpy)(5,6-Me 2bpy)(CO)Cl]+ and AgNO3 demonstrates that exchange of the chloro ligand can be achieved.
