The title compound, C(13)H(14)O(4), belongs to the class of α,β-unsaturated ketones, which have potential bactericidal, fungicidal, anti-tumor and anti-inflammatory properties. The C atoms and attached H atoms of the ethenyl part of the title mol-ecule are disordered over two orientations with refined occupancies of 0.583 (7) and 0.417 (3). Mol-ecules are connected by two inter-molecular C-H⋯O ...

The title compound, C15H13N3O3, exists in the E conformation with respect to the azo-methane C=N double bond. The pyridyl and phenyl rings form dihedral angles of 35.67 (8) and 36.65 (7)°, respectively with the central C(=O)N2C unit. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds connect the mol-ecules into chains along the b axis. Another C-H⋯O inter-action connects mol-ecules along the c-axis...

The title com pound, unreported as an insect pheromone com ponent, effectively attracted certain male Gelechiidae (genera Chionodes, M onochroa, Argolam protes) as a sin­ gle chemical. Trap captures with this chemical decreased on addition o f either (E)-3-dodecenyl acetate, (£)-3-tetradecenyl acetate or (Z )-3-tetradecen-l-ol, the sexual attractants of other, closely related species. Results o...

The title compound, C(19)H(10)F(5)NO(2), was synthesized by the 1:1 condensation of 2-methyl-8-hydroxy-quinaldine with penta-fluoro-benzaldehyde. It crystallizes with two almost identical mol-ecules in the asymmetric unit. The penta-fluoro-benzene ring is essentially coplanar with the quinoline ring, forming dihedral angles of 2.49 (17) and 8.72 (16)° in the two mol-ecules.

In the crystal of the title compound, C(19)H(14)FNO(2), the mol-ecules are linked by C-H⋯O hydrogen bonds in translational chains along the b axis. The dihedral angles formed by the quinoline system with the fluoro-benzene ring and the acet-oxy group are 8.15 (3) and 77.42 (4)°, respectively.
