Summary:The front cover picture, provided by Teruhisa Tsuchimoto and co‐workers, illustrates the usefulness of alkynyl–B(dan)s in palladium catalysis. The Tsuchimoto team demonstrates for the first time that the carbon–B(dan) bond can be directly used for the coupling with aryl(alkenyl) halides and allylic carbonates under palladium catalysis, and with acyl chlorides under palladium–copper catalysis. Moreover, the alkynyl–B(dan) worked well as a platform for synthesizing a structurally well‐defined tetraarylalkene through a triborylalkene.
