| Abstract: | Photochemical Reactions of 3-Pyrazolidone Betains. VII. Photochemical Dimerization of 3-Pyrazolidone Azomethinimines UV irradiation of 3-pyrazolidone azomethinimines 1 in methanol results in low yields in photochemical head-tail-dimerization of 1 to the hexahydrotetrazines 3 . The structure of 3 is elucidated by chemical and spectroscopic methods (IR, 1H-, 13NMR). |
