Crystal structure of 3-bromo-9-ethyl-9H-carbazole
نویسندگان
چکیده
In the title compound, C14H12BrN, the tricyclic ring system is essentially planar (r.m.s. deviation 0.026 Å). The carbon atoms of the ethyl group deviate from the mean plane by 0.148 (9) (CH2) and 1.59 (1) Å (CH3). In the crystal, H⋯π contacts [2.698-2.898 Å] shorter than the van der Waals contact distance of 3.70 Å are observed. A scalable to gram quantities selective synthesis of mono-bromine-substituted carbazole derivatives was developed.
