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. 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5, Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane
The crystal structure of the ethylacetoacetate (EAA) sodium enolate – 15 crown 5 complex (E(-)Na(+)-15C5) is described and compared with the E(-)K(+)-18C6 structure already published.Both entities are contact ion pairs externally complexed by the crown.The Na(+) cation is out of the mean plane of the crown (1.05 Angstroem).The structure of both complexes is retained in THF solution.The effects observed upon addition of crowns to E(-)M(+) enolates in THF solution (ir and kinetics) or DMSO solution (ir and conductivity) are discussed on the basis of an equilibrium between four ionic species: E(-)M(+), E(-)<*>M(+), E(-)M(+)-C, and E(-)<*>M(+)-C.Some values of eqiulibrium constants have been determined.Of special interest is the simultaneous presence of the two species E(-)M(+)-C and E(-)<*>M(+)-C when crown ether is added in excess.The position of the plateau equilibrium between these two species depends on the nature of the solvent, the cation, and the crown.Some previous results in the literature about alkylation of EAA enolates are rediscussed in relation to this plateau equilibrium.
