Abstract: | The photochemical transformations of triafulvene 6 in solvents of different type are investigated. Irradiation of 6 in methanol/ethanol leads to products which are derived from quinodimethane 7 by addition of alcohol in 1.2 or 1.6 fashion. When 6 is irradiated in acetonitrile/benzonitrile, products of complex structural type are obtained. For structure elucidation a X-ray crystallographic analysis is performed for 17a. |
