TL;DR: A series of quinoxaline derivatives was synthesized by the reaction of 3-(ω-bromoacetyl)coumarins with substituted 1,2-diaminobenzenes in the absence of a catalyst under microwave conditions as discussed by the authors.

TL;DR: Molecules of the title compound, C11H17O4P, are linked into chiral helical chains along the crystallographic b axis via O—H⋯O hydrogen bonds between the hydroxy group and an O atom of the phosphonate group.

TL;DR: In the molecule of the title compound, C9H7NOS2, the heterocycle and the phenyl ring are oriented at a dihedral angle of 72.3 (1)° and connected through C—H⋯O interactions.

TL;DR: The title compound, C12H9Cl2NO2, was prepared by the esterification of 3,7-dichloroquinoline-8-carboxylic acid with triethyl phosphite by stabilized by aromatic π–π stacking between the benzene and the pyridine rings of neighbouring molecules.
