The Cover shows a favorable interaction between a Lewis acidic boron atom and a chlorine atom on a palladium complex for boryl transfer. In their Communication, Y. Yamamoto et al. report the palladium‐catalyzed borylation of aryl chlorides with diboron reagents, surprisingly, in the absence of base. Experimental and computational studies have disclosed that smooth boryl transfer from diboron to arylpalladium chloride is promoted by strong interaction between the Lewis acidic boron and the chlorine on palladium. This is important information to achieve ideal activator‐free cross‐coupling reactions. More information can be found in the Communication by Y. Yamamoto et al. on page 2317 in Issue 14, 2016 (DOI: 10.1002/cctc.201600456).
