Still elusive: The reduction of dimethylimidazol‐2‐ylidene dichloroborane by sodium naphthalenide has been suggested to provide a borylene that cycloadds to naphthalene to make a borirane. Evidence has been provided that this borirane instead arises from coupling of a boryl radical and sodium naphthalenide. In contrast, reduction of 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene dichloroborane and
