  The Pauson-Khand Reaction: A Gas-Phase and Solution-Phase Examination Using Electrospray Ionization Mass Spectrometry

  摘要：

  A series of dicobalt hexacarbonyl complexes with charged alkyne ligands were prepared to enable the study of the Pauson-Khand reaction using ESI-MS. The hexacarbonyl complexes can be activated in the gas phase through removal of a CO ligand. The resulting pentacarbonyl ions react readily with alkenes, and no discrimination between alkenes was found for this step, indicating that alkene association is not rate determining in the intermolecular reaction. Solution-phase ESI-MS studies on a system set up for intramolecular reactivity revealed only the hexacarbonyl complex as a detectable intermediate, and the reaction was shown to have a large enthalpy and entropy of activation, consistent with ligand dissociation being rate limiting in the reaction.

  The invention relates to fluorescent/fluorogenic probes of formula (I″) or (II″): wherein Z is chosen between: —NH 2 and —OH, or in the fluorescence quencher group consisting of: —NO 2 ; —N═N—R 1 ; R 1 being any organic group that does not obscure the corresponding azo bond; —NHCO-Pept.; Pept. being a peptide residue or any organic group that does not obscure the corresponding amide bond; —O-Glyc.; Glyc. being a oligoglycoside residue that does not obscure the corresponding glycosidic bond; —O—C(O)—R 2 ; —O—P(O)(OR 2 )(OR 2 ′) and —O—S(O) 2 —R 2 ; R 2 and R 2 ′ being independently a hydrogen atom or an organic group that does not obscure the corresponding ester bond; and R a , R b , R c , R d and R e being independently a hydrogen atom or any organic group that does not obscure the corresponding arylether bond so as not to prevent its possible cleavage by a myeloperoxidase activity. It also relates to the use of these fluorescent/fluorogenic probes, for the detection of an enzyme activity, notably in order to identify/discriminate microorganisms in function of their ability to express particular enzyme activities.

  该发明涉及式(I″)或(II″)的荧光/荧光探针： 其中Z在以下选项中选择：—NH2和—OH，或者在荧光猝灭剂基团中选择：—NO2；—N═N—R1；其中R1是任何不遮挡相应偶氮键的有机基团；—NHCO-Pept.；Pept.是肽残基或任何不遮挡相应酰胺键的有机基团；—O-Glyc.；Glyc.是不遮挡相应糖苷键的寡糖苷残基；—O—C(O)—R2；—O—P(O)(OR2)(OR2′)和—O—S(O)2—R2；其中R2和R2′独立地是氢原子或不遮挡相应酯键的有机基团；以及Ra、Rb、Rc、Rd和Re独立地是氢原子或任何不遮挡相应芳基醚键的有机基团，以便不阻止其可能被髓过氧化酶活性水解。 该发明还涉及这些荧光/荧光探针的用途，用于检测酶活性，特别是为了根据微生物表达特定酶活性的能力来识别/区分微生物。

  A new type of highly temperature stable ionic liquid (IL) with strongly temperature dependent nanostructures is reported. The molecular design relies on the use of a liquid polymer with an ionic liquid headgroup, introducing liquid properties by both the polymeric and the ionic liquid (IL) headgroup. The IL polymers (poly-(isobutylene)s) 3a-3c (PIB-ILs) were prepared by a combination of living carbocationic polymerization (LCCP) and subsequent "click" chemistry for attachment of methylimidazolium (3a), pyrrolidinium (3b), and triethylammonium cations (3c). All three investigated PIB-ILs exhibited pronounced nanostructural organization at room temperature depending strongly on the nature of the anchored cation. Whereas the morphology of the imidazolium-based PIN-IL 3a shows high thermal stability up to the decomposition temperature, order-order (OOT) and lattice disorder-order transitions (LDOT) characteristic for common ionomers could be observed in the case of pyrrolidinium 3b and ammonium-based 3c PIB-ILs. Control of flow behavior as well as adjustable relaxation times from the liquid to the viscoelastic regime can be adjusted by choice of the appropriate IL headgroup.
