(E,E)-3,6-Bis(styryl)pyridazines (3a-t) bearing 2, 4 or 6 alkoxy chains were prepared by applying the Siegrist reaction of 3,6-dimethylpyridazine (13) and the corresponding azomethines 10a-t. The transversal dipole moment of these calamitic compounds effe

The 1,3-distyrylbenzenes 3, containing up to seven alkoxy groups, are subjected to the oxidative photocyclization.Elimination of methanol (3bb -> 7bb, 3bf -> 7bf) and quinone oxidation can occur as competitive or consecutive reactions in the formation of the products 6, 7, and 8.Selfsensitized generation of singlet oxygen by 6bf can lead to endoperoxide formation (6bf -> 11).
