- Аннотация: 2-Benzo[b]thienyl fulgides and fulgimides containing bulky diphenylmethylene substituents were synthesized in the form of theirring-opened E- or Z-isomers. In contrast to the majority of known fulgides/fulgimides, that form colored ring-closed structuresunder UV irradiation, the obtained compounds undergo an irreversible transformation leading to decoloration of their solutions.This rearrangement with the formation of the dihydronaphthalene core appeared to be by 2–3 orders of magnitude more efficientthan for the known diphenylmethylene(aryl(hetaryl))fulgides. The molecular structures of E- and Z-isomers and of products of thephotoinduced rearrangement completed by 1,5-H shift reaction, 3a,4-dihydronaphtho[2,3-c]furans(pyrroles) C, were establishedbased on the data of 1H and 13C NMR spectroscopy and X-ray diffraction studies.
