need is an open vial! The direct α arylation of cyclic alkylamines (see scheme) requires an open vial, as the hydrogen atom involved in the C(sp3)H‐activation process is ultimately released as hydrogen gas. Reports on the formation of hydrogen gas in direct transition‐metal‐catalyzed functionalizations are still rare. Open‐vial reactions proved crucial to this directarylation procedure as, upon sealing
