  • Ru-Catalyzed (<i>E</i>)-Specific <i>ortho</i>-C–H Alkenylation of Arenecarboxylic Acids by Coupling with Alkenyl Bromides
    作者:Zhiyong Hu、Florian Belitz、Guodong Zhang、Florian Papp、Lukas J. Gooßen
    DOI:10.1021/acs.orglett.1c00956
    日期:2021.5.7
    alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)-configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.
    在[对-异丙基)RuCl 2 ] 2的存在下,(E)-构型的烯基溴化物与芳族羧酸盐偶合形成邻-乙烯基苯甲酸。这种C–H乙烯基化无需任何活化的膦配体就可以高产率进行,并且具有出色的官能团耐受性。从烯基溴化物的常见(E / Z)混合物开始,仅形成(E)构型的乙烯基芳烃或二烯。机理研究表明,实现这种选择性的原因是,(E)-构型的烯基溴化物经历了平滑的偶联,而(Z异构体会随着炔烃的形成而迅速消除。
  • Rhodium-Catalyzed Regioselective Olefination Directed by a Carboxylic Group
    作者:Satoshi Mochida、Koji Hirano、Tetsuya Satoh、Masahiro Miura
    DOI:10.1021/jo200509m
    日期:2011.5.6
    The ortho-olefination of benzoic acids can be achieved effectively through rhodium-catalyzed oxidative coupling with alkenes. The carboxylic group is readily removable to allow ortho-olefination/decarboxylation in one pot. alpha,beta-Unsaturated carboxylic acids such as methacrylic acid also undergo the olefination at the beta-position. Under the rhodium catalysis, the cine-olefination of heteroarene carboxylic acids such as thiophene-2-carboxylic acid proceeds smoothly accompanied by decarboxylation to selectively produce the corresponding vinylheteroarene derivatives.
  • Synthesis of Stilbene and Distyrylbenzene Derivatives through Rhodium-Catalyzed<i>Ortho</i>-Olefination and Decarboxylation of Benzoic Acids
    作者:Satoshi Mochida、Koji Hirano、Tetsuya Satoh、Masahiro Miura
    DOI:10.1021/ol1027392
    日期:2010.12.17
    Ortho-substituted benzoic acids efficiently undergo precisely ordered ortho-olefination/decarboxylation upon treatment with styrenes in the presence of a rhodium catalyst and silver salt oxidant to afford the corresponding meta-substituted stilbene derivatives. The selective syntheses of 1,3- and 1,4-distyrylbenzenes have also been realized through the reactions of simple benzoic acid and phthalic
