Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Introducing a new discovery about 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, name: (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.
The neutral complexes [Ru(CO)(dpa)(PR3)Cl2] (R = Ph (1) or p-tol (2); dpa = 2,2?-dipyridylamine) were synthesized by the reaction of [Ru(CO)(dmf)(PR3)2Cl2] (dmf = N,N-dimethylformamide) and the dpa ligand, while the cationic carbonyl hydride complexes [Ru(CO) (N-N)(PPh3)2(H)]Cl were synthesized by reaction of [Ru(CO)(PPh3)3Cl(H)] and the appropriate N-N ligand [N-N = 2,2?-bipyridine = bipy (3), 2,2?-4,4?dimethyl-bipyridine = dmb (4) and 2,2?-dipyridylamine = dpa (5)]. The complexes were characterized by NMR (31P, 1H and HMBC 1H-31P), FTIR, elemental analysis and X-ray diffraction. The molecular structure of [Ru(CO)(dpa)(PPh3) Cl2] (1) was determined by X-ray crystallography. The crystal packing is stabilized by strong (CH3)O-H…Cl and N-H…OH(CH3) hydrogen bonds between symmetry-related molecules leading to the formation of dimers. Complexes 1-6 were evaluated as pre-catalysts for the reduction of acetophenone under transfer-hydrogenation conditions using isopropanol as hydrogen source, and conversions up to 86 % in 4 h were achieved.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: (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.
