2-Bromo-3-hydroxy-6-methylpyridine
In the title compound, C6H6BrNO, the Br atom is displaced from the pyridine ring mean plane by 0.0948 (3) Å, while the hydroxyl O atom and the methyl C atom are displaced by 0.0173 (19) and 0.015 (3) Å, respectively. In the crystal, mol-ecules are linked via O-H⋯N hydrogen bonds, forming chains propagating along the a-axis direction. These chains are linked by C-H⋯Br hydrogen bonds, forming cor...
متن کامل3-Bromo-6-nitro-1-(prop-2-ynyl)-1H-indazole
In the title compound, C(10)H(6)BrN(3)O(2), the indazole fused-ring system is nearly planar (r.m.s. deviation = 0.008 Å); its nitro substituent is nearly coplanar with the fused ring [dihedral angle = 4.5 (2)°]. In the crystal, adjacent mol-ecules are linked by weak acetyl-ene-nitro C-H⋯O hydrogen bonds, generating a helical chain running along the b axis.
متن کامل2-(6-Bromo-3-pyridyl)-8-methylimidazo[1,2-a]pyrazine
The structure of the title compound, C(12)H(9)BrN(4), prepared by the reaction of 2-bromo-1-(6-bromo-3-pyrid-yl)ethanone with 2-amino-3-methyl-pyrazine indicates that the compound with the bromo-pyridyl substituent at position 2 of the imidazopyrazine fused-ring system represents the major product of this reaction. The plane of the pyridine ring forms a dihedral angle of 16.2 (2)° with the esse...
متن کاملSYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
متن کامل2-Bromo-3-nitrobenzaldehyde
The title compound, C(7)H(4)BrNO(3), was isolated as a by-product while attempting to prepare a diselenide. There is a close intra-molecular Br⋯O contact [2.984 (2) Å]. The mol-ecules form loosely associated dimers held together by weak inter-molecular Br⋯O inter-actions with the nitro O atoms [Br⋯O = 3.179 (3) Å]. As a result of these inter-actions, there is also a close Br⋯Br inter-molecular ...
