9-Ethyl-3-(2-methyl­benzo­yl)-9H-carbazole

In the title compound, C(22)H(19)NO, the dihedral angle between the benzene ring and the carbazole ring system 77.1 (1)°.. The crystal structure is stabilized by inter-molecular aromatic π-π inter-actions between the benzene ring and the pyrrole ring of the carbazole system of neighbouring mol-ecules [centroid-centroid distance = 3.617 (4) Å]. In addition, the crystal structure exhibits a weak ...

9-Ethyl-9H-carbazole-3-carbaldehyde

The title mol-ecule, C(15)H(13)NO, approximates a planar conformation except for the alkyl chain (ethyl group) bonded to the N atom with a maximum deviation from the least-squares plane through the 15 planar atoms of 0.120 (2) Å for the O atom. The distance of the formyl O atom from the plane of the carbazole ring is 0.227 (2) Å. The N-C bond lengths in the central ring are significantly differ...

Ethyl 4-hydr­oxy-9-tosyl-9H-carbazole-3-carboxyl­ate

In the title compound, C(22)H(19)NO(5)S, the carbazole skeleton is nearly planar [maximum deviation = 0.043 (1) Å] with the pyrrole ring oriented at dihedral angles of 2.32 (6) and 1.77 (6)° with respect to the adjacent benzene rings. The dihedral angle between the benzene ring of the tosyl group and the carbazole skeleton is 82.25 (5)°. Intra-molecular O-H⋯O hydrogen bonding results in the for...

9-Ethyl-3,6-diformyl-9H-carbazole

The structure of the title compound, C(16)H(13)NO(2), was determined as a part of a project on the synthesis of new compounds which can make two-photon absorptions. In the crystal structure, both aldehyde groups are located within the carbazole plane. One of these groups is disordered and was refined using a split model with site-occupation factors for each position of 0.5.

Crystal structure of 3-bromo-9-ethyl-9H-carbazole

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...
