Nickel‐Catalyzed Sonogashira Couplings: Extending the Reaction Scope to Aryl Bromides and Chlorides

Elena Braconi,

et al.

Abstract: The alkyne motif is present in several naturally occur‐ring molecules and specialty chemicals. The Sonogashira reaction is recognized as one of the most exploited methods for the synthesis of substituted alkynes. While palladium catalysts have been traditionally employed, recent efforts have been directed towards developing alternatives based on Earth‐abundant metals such as nickel. However, nickel‐catalyzed Sonogashira couplings still present important substrate limitations. While more reactive aryl iodides h… Show more
