6-Bromo-1-butylindoline-2,3-dione
There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)BrNO(2). The C-C bond lengths of the two carbonyl C atoms of the five-membered rings are distinctly longer than a normal Csp(2)-Csp(2) single bond. One of the mol-ecules makes parallel self-coupled (inversion) dimers by π-π inter-actions with phen-yl-phenyl inter-planar distances of 3.403 (2) Å. The oth...
متن کاملCrystal structure of (5Z)-5-(5-bromo-2-hydroxybenzylidene)-1,3-thiazolidine-2,4-dione
In the title compound, C10H6BrNO3S, the dihedral angle between the thia-zolidine ring (r.m.s. deviation = 0.014 Å) and the benzene ring is 5.78 (14)°. The S atom of the heterocyclic ring is syn to the OH group attached to the benzene ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(8) loops. The dimers are linked into [001] ribbons by pairwise O-H⋯...
متن کاملCrystal structure of 2-(5-bromo-2-hydroxybenzylidene)-2,3-dihydro-1H-indene-1,3-dione
The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)° between the planes of the five- and six-membered rings. An intra-molecular C-H⋯O hydrogen bond between the attached benzene...

Isatin (1H-indole-2,3-dione) is an endogenous compound that has been identified in humans and possesses a wide range of biological activities, such as anxiogenic and sedative activities. A variety of biological activities are associated with isatin, including central nervous system (CNS) activities (Raj, 2012). The single crystal X-ray diffraction study of the title compound has been made and i...

interpret the detailed mechanisms of reactions of tautomeric heterocycles properly. The correct dominant tautomeric structure also makes it possible to interpret the biological activity and functions of potential tautomeric heterocycles.1 Many of these aza/deaza analogues of purine and their nuclosides have drawn considerable interest in biological activity. Compound 6-amino-1,2,4-triazolo[3,4-...
