Mono‐, Di‐, Tri‐, Tetra‐, Penta‐and Hexaphenylbullvalenes Lithium diphenylcuprate reacts with the corresponding bromobullvalenes to yield the phenylbullvalenes 1–6 , whose substitution patterns are deduced from their 1 H‐NMR spectra. Starting with triphenylbullvalenes 3 some isomers show a relatively high kinetic stability which culminates in the case of the hexaphenylbullvalenes 6a and 6b in the loss of the phenomenon of fluctuating structure for the bullvalene skeleton.
