acceptorless dehydrogenation is an environmentally benign way to desaturate organic compounds. This process is traditionally accomplished with transition‐metal‐based catalysts. Herein, a borane‐catalyzed, metal‐free acceptorless dehydrogenation of saturated N‐heterocycles is disclosed. Tris(pentafluorophenyl)borane was identified as a versatile catalyst, which afforded several synthetically important N‐heteroarenes
