A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 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, molecular formula is C12H22O11.

Addition of di(2-pyridyl)amine (dpa) to a solution formed by reaction of [Ru(CO)2Cl2]n with NaOAc resulted in the precipitation of [Ru(OAc)(CO)2(dpa)]2, a complex containing a rare example of monodentate dpa coordination. X-ray crystallography revealed a dinuclear complex with a Ru-Ru bond, having two cis-carbonyls on each ruthenium trans to oxygen donors of two mu-acetate ligands and a monodentate dpa approximately colinear with the Ru-Ru bond. A variable temperature 1H NMR study of this complex indicated fluxional behaviour of the dpa ligand in solution at room temperature, with the spectrum at 243 K corresponding to that predicted from the solid state structure. Heating of [Ru(OAc)(CO)2(dpa)]2 in ethanol formed [Ru2(OAc)(CO)4(dpa)2]+, which was isolated as the acetate salt. The X-ray structure of this complex and the analogous benzoate bridged [Ru2(PhCO2)(CO) 4(dpa)]Cl confirmed the presence of a diruthenium(I) core with terminal chelating dpa ligands and bridged by one carboxylate and two carbonyl ligands.
