چکیده
The title mol-ecule, C(9)H(5)Br(2)N, is almost planar, with an r.m.s. deviation of 0.027 Å. The dihedral angle between the aromatic rings is 1.5 (3)°. In the crystal, π-π stacking inter-actions are present between the pyridine and benzene rings of adjacent mol-ecules [centroid-centroid distances = 3.634 (4) Å], and short Br⋯Br contacts [3.4443 (13) Å] occur.

Synthesis and photophysical properties of 2-aryl-6,8-bis(arylethenyl)-4-methoxyquinolines.
Iodine-methanol mediated oxidative-aromatization of 2-aryl-6,8-dibromo-2,3-dihydroquinolin-4(1H)-ones afforded the corresponding 2-aryl-6,8-dibromo-4-methoxy-quinolines in high yield and purity. The isomeric 1-(2-amino-3,5-dibromophenyl)-3-aryl-2-propen-1-ones reacted with iodine in methanol afford in a single pot operation the corresponding 2-aryl-6,8-dibromo-4-methoxyquinoline (major) and 2-...
متن کاملSynthesis and photophysical property studies of the 2,6,8-triaryl-4-(phenylethynyl)quinazolines.
The 2-aryl-6,8-dibromo-4-chloroquinazolines derived from the 2-aryl-6,8-dibromoquinazolin-4(3H)-ones were subjected to the Sonogashira cross-coupling with terminal acetylenes at room temperature to afford novel 2-aryl-6,8-dibromo-4-(alkynyl)quinazoline derivatives. Further transformation of the 2-aryl-6,8-dibromo-4-(phenylethynyl)quinazolines via Suzuki-Miyaura cross-coupling with arylboronic a...
متن کاملComplete Genomic Sequences of Two Salmonella enterica subsp. enterica Serogroup C2 (O:6,8) Strains from Central California
Salmonella enterica subsp. enterica strains RM11060, serotype 6,8:d:-, and RM11065, serotype 6,8:-:e,n,z15, were isolated from environmental samples collected in central California in 2009. We report the complete genome sequences of these two strains. These genomic sequences are distinct and will provide additional data to our understanding of S. enterica genomics.
متن کاملDesign, synthesis and anticonvulsant activity of some new 6,8-halo-substituted-2h-[1,2,4]triazino[5,6-b]indole-3(5h)-one/-thione and 6,8-halo-substituted 5-methyl-2h-[1,2,4]triazino[5,6-b]indol-3(5h)-one/-thione
A new series of 6,8-halo-substituted-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-one/-thione and 6,8-halo-substituted 5-methyl-2H-[1,2,4]triazino[5,6-b]indol-3(5H)-one/-thione (5a-5l) were designed and synthesized keeping in view of the structural requirement of pharmacophore. The above compounds were characterized by thin layer chromatography and spectral analysis. Anticonvulsant activity of the syn...
متن کاملTwo isomeric 10-methyl-8-phenyl-11-pyridyl-6,8-dihydro-5H-benzo[f]pyrazolo[3,4-b]quinolines: cyclic hydrogen-bonded tetramers versus isolated molecules.
The molecules of 10-methyl-8-phenyl-11-(3-pyridyl)-6,8-dihydro-5H-benzo[f]pyrazolo[3,4-b]quinoline, C26H20N4, (I), are linked by a single C-H...N hydrogen bond into cyclic R(4)(4)(12) tetramers generated by a -4 axis. In isomeric 10-methyl-8-phenyl-11-(4-pyridyl)-6,8-dihydro-5H-benzo[f]pyrazolo[3,4-b]quinoline, (II), which crystallizes with Z' = 2 in space group P2(1)2(1)2, the two independent ...
