3-Chloro-6-{4-[3-(trifluoro-meth-yl)phen-yl]piperazin-1-yl}pyridazine
Abstract:
The title compound, C(15)H(14)ClF(3)N(4), was synthesized from 3,6-dichloro-pyridazine and 1-[3-(trifluoro-meth-yl)phen-yl]piper-azine. The piperazine ring is flanked by 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings and adopts a chair conformation, whereas the 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings are planar, with maximum deviations of 0.0069 (13) and 0.0133 (14) Å, respectively. The crystal structure is stabilized by weak inter-molecular C-H⋯N hydrogen-bond inter-actions.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
