4-(3,4-Methyl­ene­dioxy­phenoxy)­phthalo­nitrile

In the structure of the title compound, C₁₅H₈N₂O₃, the phthalo­nitrile group and the 3,4-methyl­ene­dioxy­phenoxy substituent are twisted with respect to one another by 58.89 (3)°. In the crystal structure, the mol­ecules are stacked in the a-axis direction and are connected via weak C—H...N intermolecular contacts into chains, which extend in the direction of the c axis.

2-Acetyl-3-amino-1-benzo­furan

The title compound, C₁₀H₉NO₂, displays the characteristic features of a benzo­furan derivative. The molecular structure is nearly planar with an intramolecular N—H...O hydrogen bond involving the amino group and the acetyl carbonyl O atom. In the crystal structure, there are intermolecular N—H...O and C—H...O interactions, which help to stabilize the structure.

(E)-2-[(2-Morpholinoethyl­imino)meth­yl]phenol

The title compound, C₁₃H₁₈N₂O₂, exists in the enol–imine tautomeric form with a strong intra­molecular O—H...N hydrogen bond [O...N = 2.5795 (18) Å], and the morpholine ring adopts an almost perfect chair conformation.
