A trimethylenemethane (TMM) derivative 12., In which the parent TMM is π-extended by the symmetric Insertion of three pyridine rings Into the C-C bonds of TMM, has been synthesized by the alkali metal reduction of the Isolated corresponding dication. Although the frozen-glass X-band cw-ESR spectrum of 12. gave unresolved fine structures due to the small ZFS parameters, pulsed ESR two-dimensional electron spin transient nutation (2D-ESTN) spectroscopy unambiguously can afford to Identify diradical 1 2. as a triplet species.
