Improved Palladium‐Catalyzed Sonogashira Coupling Reactions of Aryl Chlorides

Well matched: Novel palladium/heteroaryl-phosphines are introduced for Sonogashira reactions of aryl and heteroaryl chlorides including challenging substrates (see scheme). The desired coupling reactions proceed smoothly and tolerate various functional groups. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
