✦ Synopsis

200 mL) was acidified with 3 drops of 32% HCI and stirred for 15 min at 50°C (exclusion of light). After extraction with CH,CI,, the organic phase was dried (Na,SO,) and purified on silica gel (20 8). After removal of the solvent there remained 0.53 g (72%) of a crystalline product. For further purification the substance was recrystallized from CH,CI,/Et,O; yield 0.42 g (57 %), colorless platelets. M.p. 135-137 "C (decomp.), noticeable decomposition above 120 "C.

The syn dimer of cyclobutadiene (tricyclo[4.2.0.0(2.5)]octa-3,7-diene, TOD) is subjected to ionization under different conditions and the resulting species are probed by optical and ESR spectroscopy. By means of quantum chemical modelling of the potential energy surfaces and the optical spectra, it
