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.

Emission studies of hetero-bischelated iridium(III)-diimine complexes
Two mixed-ligand complexes, cis-[Ir(bipy)(HDPA)Cl2]Cl and cis-[Ir(phen)(HDPA)Cl2]Cl (where bipy = 2,2?-bipyridine, phen = 1,10-phenanthroline, and HDPA = 2,2?-dipyridylamine), have been synthesized and characterized. Both complexes show spin-allowed pi-pi* bands in the UV region. Besides, spin-allowed and spin-forbidden charge transfer bands are also observed in the vicinity of 24.8 and 19.5 kK, respectively. The magnitude of the polarization, P, in the excitation polarization spectra obtained for the two complexes indicate that both luminophores behave as linear oscillator corresponding to the symmetry lower than C2upsilon of the two complexes. The emission spectra of both cis-[Ir(bipy)(HDPA)Cl2]+ in neutral and cis-[Ir(phen)(HDPA)Cl2]+ in slightly acidified EtOH-MeOH solvent (4:1 v/v) at 77 K, exhibit 3MLCT phosphorescence at 16-22 kK with lifetimes near 18 mus and a single vibration progression of 1240 and 1300 cm-1, respectively. The property that the emission energy becomes smaller while the polarity of solvent increases is consistent with the orbital nature of 3MLCT state. The emission energies of both complexes are nearly constant in acidic EtOH-MeOH solvent and are 3.1-3.3 kK smaller in basic solvent than that in the neutral one. The emissions of both complexes in the basic case are assigned as 3MLCT emission caused by the complexes of deprotonated form, cis-Ir(bipy)(DPA)Cl2 and cis-Ir(phen)(DPA)Cl2, with lifetimes of approximately 19 mus.
