Enamides 3a-c and 6 crystallize in cx-packing modes with short.intermolecular distances of 3.7-4.0/~ between alkene carbon atoms of adjacent molecules related by a center of symmetry. Irradiation at 350 nm of these crystalline tertiary phenylethenyl enamides affords head-to-tall dimers 8a-c and 9, r
The photodimerization of benzo-annellated acridizinium derivatives, namely naphtho[1,2-b]quinolizinium and naphtho[2,1-b]quinolizinium bromide, has been investigated in solution and in the solid state. Irradiation of the naphthoquinolizinium salts in solution gave all possible regioisomers in an uns
