The BB bond is the basic center in the azadiboriridine 1 . This is shown by the observation that reaction with the Lewis acid BH 3 affords the novel, nonclassical bicyclobutane derivative 2 in 95% yield. According to electron‐counting rules, 2 may also be regarded as a nido derivative of a trigonal‐bipyramidal compound. Ab initio calculations on the parent compound nido ‐NB 3 H 6 confirm the experimental findings (R = t Bu).
