The photochemistry of the vinyl substituted (E)-3-(anthran-9-yl)propenoates and (E)-9-(aroylethenyl)anthracenes as well of their reduced derivatives has been studied at lambda = 254 nm and at lambda= 352 nm. At lambda = 254 nm and lambda= 352 nm, the 9-vinyl substituted anthracenes undergo E/Z-isomerization, while their reduced derivatives undergo [4+4]-dimerisation reactions at lamda = 352 nm. An X-ray crystal structure shows the [4+4]-photoadducts to be head-to-tail. The photochemistry of cycloadducts of (E)-3-(anthran-9-yl)propenoates and (E)-9-(aroylethenyl)anthracenes with maleimides and other activated dienophiles show a number of reactions, among them retro-cleavage of the cycloadducts to the respective anthracenes.

In the crystal of the title compound, C11H14O4, the aromatic ring is almost coplanar with the 2-position meth-oxy group with which it subtends a dihedral of 0.54 (2)°, while the 5-position meth-oxy group makes a corresponding dihedral angle of just 5.30 (2)°. The angle between the mean planes of the aromatic ring and the propionic acid group is 78.56 (2)°. The fully extended propionic side chain is in a trans configuration with a C-C-C-C torsion angle of -172.25 (7)°. In the crystal, hydrogen bonding is limited to dimer formation via R 2 (2)(8) rings. The hydrogen-bonded dimers are stacked along the b axis. The average planes of the two benzene rings in a dimer are parallel to each other, but at an offset of 4.31 (2) Å. Within neighbouring dimers along the [101] direction, the average mol-ecular benzene planes are almost perpendicular to each other, with a dihedral angle of 85.33 (2)°.

o-Alkoxybenzamides are known to have biological activity. Thus, a group of o-methoxybenzamides constitutes dopamine receptor antagonists. Others, such as o-hexyloxybenzamide, have been found to have antifungal activity. In our search for cocrystal formation utilizing benzamides with the aim of improving solubility, stability and bioavailability during application of the molecules, we have first looked at the single crystal X-ray structures of the three o-alkoxybenzamides, o-allyloxybenzamide (1), o-propoxybenzamide (2), and o-pentoxybenzamide (3).
