The 1,2‐diboretanide ring inversion barrier for 2 (19.5 kcal mol −1 determined by 1 H NMR) is the largest among all the known isoelectronic 2π‐electron homoaromatic analogues. The X‐ray structure analysis of 2 , which was synthesized from 1 (R = H) or 3 (Dur = 2,3,5,6‐tetramethylphenyl), reveals a short central C‐B bond (171.1 pm).
