Three novel arylated chloro- and methoxy-1,3-butadienes were prepared and studied by a combination of spectroscopic (UV/vis, IR and NMR) and X-ray crystallographic methods. Influence of substituent on the molecular conformation and crystal packing (i.e. intermolecular interactions) was studied. It was predicted that the differences in electronic and steric effects of two chlorine atoms in comparison to two methoxy groups as substituents at different locations in the molecule would provide various packing of the molecules and cause different assumptions for the photochemical behaviour.
