The pentalene derivative 2 is only inductively stabilized. It was obtained by reaction of the dihydro derivative 1 with nickel peroxide. Comparison of the spectroscopic data with the results of MNDO calculations indicates that the Kekulé structure shown here dominates; that is, the bonds are fixed.
