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, HPLC of Formula: C10H20O5
X-Ray crystallography of dichlorodicyano- or tetrachloro-p-benzoquinone salts with polyether-ligated alkali metals reveals discrete supramolecular complexes: [{M(L)A}2]. They show pairs of co-facial p-benzoquinone anions (A-) arranged at close interplanar separation: r pi? 2.9 A characteristic of ion-radical pi-dimers. Moreover, these pi-bonded anions are tethered by couples of alkali-metal cations (M+) nested in the crown-ether (L) cavities. The structures of such assemblies are compared to the non-tethered pi-dimers (with 1 : 1 cation/anion coordination), as well as to the separated dianionic [A 2]2- and monoanionic [A2]-=pi- dyads. Such a comparison reveals that, contrary to electrostatic implications, counter-ion coordination (or monomer charge decrease) is accompanied by increase of the interplanar separations (rpi) between pi-bonded p-benzoquinones. In addition, counter-ion bridges switch the lateral monomer offset from longitudinal in the separated pi-dimers to transversal in the tethered assemblies. In dichloromethane, equilibrium constants of pi-dimers formation are higher for the ion-paired salts as compared to those of the separated analogues, but the enthalpies of pi-dimerization (DeltaH D) are essentially independent of counter-ions. Thus, structural (rpi) and thermodynamic (DeltaHD) features of the anionic p-benzoquinone pi-dimers suggest a superior compensation of coulombic interactions and relatively minor role of counter-ions in the long-distance ion-radicals pi-bonding. the Owner Societies.
