Anwendungsbeispiele Englisch
  • Yet another method involves the Sonogashira coupling of iodobenzene with trimethylsilylacetylene, followed by removal of the trimethylsilyl group using TBAF.
  • DIPEA can be used as a base in a number of transition metal catalyzed cross-coupling reactions, such as the Heck coupling and the Sonogashira coupling (as illustrated below).
  • Sonogashira coupling has found widespread use in coupling aryl halides with alkynes. TONs upwards of 2,000,000 and low catalyst loadings of 0.005 mol % can be achieved with PNP-based catalysts.
  • The Sonogashira reaction has become so well known that often all reactions that use modern organometallic catalyst to couple alkyne motifs are termed some variant of "Sonogashira reaction", despite the fact that these reactions are not carried out under true Sonogashira reaction conditions.
  • Acetylides are sometimes intermediates in coupling reactions. Examples include Sonogashira coupling, Cadiot-Chodkiewicz coupling, Glaser coupling and Eglinton coupling.

  • Sp2-hybridized carbon groups attached to tin are the most commonly used coupling partners, and sp3-hybridized carbons require harsher conditions and terminal alkynes may be coupled via a C-H bond through the Sonogashira reaction.
  • Menshutkin reaction, Sonogashira coupling, Suzuki-Miyaura coupling and the production of ureas have been carried out in dihydrolevoglucosenone.
  • and a variety of cross-coupling reactions, such as Suzuki, Sonogashira, Stille, Buchwald–Hartwig reactions.
  • This compound was then subjected to further iodination and sequential Sonogashira couplings to generate a receptor for anions such as Cl− and Br−.
  • Pd-NHC complexes used in Sonogashira cross-coupling effect temperature stability in the complex.

  • The ansa-bridging macrolactone was constructed following the first Sonogashira coupling, using the Shiina macrolactonization.
  • It participates in a number of classical reactions including Suzuki-Miyaura couplings, Sonogashira couplings, Huisgen cycloadditions, and borylations.
  • Suzuki-Miyaura coupling, Buchwald-Hartwig amination for producing aryl amines from aryl halides, and Sonogashira coupling, etc.
  • Trimethylsilylacetylene is used in Sonogashira couplings as the equivalent of acetylene.
  • show an excellent activity in various palladium-catalyzed coupling reactions, including Suzuki reactions, Sonogashira couplings and Buchwald–Hartwig reactions.
