BLA=0? Not so fast! A series of tetraarylcumulenes up to the length of a [9]cumulene has been synthesized and analyzed by X‐ray crystallography. The structural data show a distinct reduction in bond‐length alternation (BLA) as a function of molecule length, but this trend appears to reach a limit before a cumulenic structure with BLA=0 is achieved.
