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.

A rare earth alloy as a synthetic reagent: Contrasting homometallic rare earth and heterobimetallic outcomes
Reaction of LaNi5 with 2,2?-dipyridylamine (HNpy 2) at 170C under vacuum gave crystals of dimeric [La(Npy 2)3]2 as a previously unknown eight-coordinate isomer (1a) (two mu-eta2:eta2 and two terminal chelating (Namide,Npy) Npy2 ligands), which reverts to the known ten coordinate isomer (1b) on recrystallisation from THF/PhMe, thereby establishing linkage isomerism of a [Ln(Npy2) 3]2 complex for the first time. Reaction of 8-hydroxyquinoline (HOQ) with excess LaNi5 alloy at 190C resulted in extraction of both metals and the formation of heterobimetallic [Ni2La(OQ)7] (2). The trinuclear complex has two terminal, fac-octahedral nickel(II) sites, each bound to three chelating 8-quinolinolate anions which bridge through the oxygen atoms to the lanthanum(III) centre. The eight-coordinate lanthanum environment is completed by a chelating OQ ligand. the Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2006.
