Abstract

Abstract : The front cover picture illustrates a palladium catalyst smoothly producing cyclopropylarenes, like an oyster, a local specialty in Hiroshima, producing clean water. In the direct Suzuki−Miyaura coupling, dan‐substituted, Lewis acidity‐diminished cyclopropylboronamides can be activated by t ‐BuOK. The increased s‐character of the cyclopropyl−B(dan) bond should be the key to transmetalation with the palladium catalyst. Details can be found in the Communication by Hiroto Yoshida and co‐workers (M. Koishi, K. Tomota, M. Nakamoto, H. Yoshida, Adv. Synth. Catal . 2023, 365, 682–686; DOI: 10.1002/adsc.202201141 ).
