  Chiral Ru-Based Complexes for Asymmetric Olefin Metathesis:  Enhancement of Catalyst Activity through Steric and Electronic Modifications

  摘要：

  Design, synthesis, characterization, and catalytic activity of six enantiomerically pure Ru-based metathesis catalysts are disclosed (3a-3f). The new chiral catalysts were prepared through steric and electronic alterations of the parent catalyst system (3). The present studies indicate that the effect of structural modifications of chiral complex 3 does not always correspond to those of the related achiral complexes. The present findings illustrate that modified Ru complexes (3e and 3f) deliver reactivity levels that are more than 2 orders of magnitude higher than 3. Reactivity and physical data are provided that shed light on the origin of activity differences. Some members of the new generation of chiral Ru catalysts promote asymmetric ring-opening (AROM) and ring-closing (ARCM) metatheses that cannot be effected by the first generation chiral catalyst (3).

  三氟甲基和3,3,3-三氟丙烯基取代的芳香族化合物通过相应碳二硫代酯的氧化脱硫-氟化的简便合成

  摘要：

  使用 [n-Bu4N]H2F3 和 1,3-二溴-5,5-二甲基乙内酰脲 (DBH) 在极其温和的条件下，通过容易获得的甲基芳烃二硫代碳酸酯的氧化脱硫-氟化反应很容易合成三氟甲基取代的芳香族化合物。使用 N-溴代琥珀酰亚胺或 N-碘代琥珀酰亚胺代替 DBH 得到二氟（甲硫基）甲基取代的芳烃。以类似的方式，3,3,3-三氟丙烯基取代的芳族化合物很容易从相应的α,β-不饱和碳二硫代酸酯中制备。

  Trifluoromethyl-substituted aromatic compounds were obtained by oxidative desulfurization-fluorination reaction of methyl arenedithiocarboxylates using n-Bu4N+H2F3>− and 1,3-dibromo-5,5-dimethylhydantoin (DBH). Use of N-bromosuccinimide or N-iodosuccinimide instead of DBH afforded difluoro(methylthio)methyl-substituted aromatics.
