(Z)-tert-Butyl 2-(4-amino-9H-fluoren-9-ylidene)acetate
The title compound, C(19)H(19)NO(2), obtained as an almost equimolar mixture (as shown by (1)H NMR) with the E isomer through a Wittig reaction between 4-amino-9H-fluoren-9-one and the stabilized ylide Ph(3)P=CHCO(2)C(CH(3))(3), was obtained pure in the Z configuration following crystallization from toluene. The mol-ecule shows a planar arrangement of the ring system and the new double bond, wh...
متن کامل9-(4-Bromophenyl)-3,6-di-tert-butyl-9H-carbazole
The asymmetric unit of the title compound, C(26)H(28)BrN, contains two independent mol-ecules in which the carbazole rings are almost planar, with r.m.s. deviations of 0.0212 (1) and 0.0229 (1) Å. The dihedral angles between the carbazole ring system and the pendent benzene ring are 60.5 (1) and 56.3 (1)° in the two mol-ecules. In the crystal, mol-ecules are linked into chains along the b axis ...
متن کاملN-(9H-Fluoren-9-ylidene)-4-methylaniline
In the title compound, C(20)H(15)N, the fluorene unit is essentially planar [r.m.s. deviation 0.0334 Å] and the benzene ring bound to the imine N atom bears a methyl group which is nearly coplanar [dihedral angle 0.5 (1)°]. The dihedral angle between the substituent benzene ring and the 9H-fluoren-9-imine unit is 71.1 (3)°. Inter-molecular π-π inter-actions between the benzene rings of adjacent...
متن کامل2-(9H-Fluoren-9-ylidenemethyl)thiophene
The title compound, C(18)H(12)S, contains a thio-phene ring which is disordered by rotation of 180° about the linking C-C bond. The site occupancies of the major and minor components of the disordered ring are 0.900 (3) and 0.100 (3), respectively. In one of these disordered components, the mol-ecule is stabilized by an intra-molecular C-H⋯S hydrogen bond. The compound was synthesized in good y...
متن کامل9-Chloromethyl-9-[(9H-fluoren-9-yl)methyl]-9H-fluorene
In the title compound, C(28)H(21)Cl, the dihedral angle between the two fluorene ring systems is 71.97 (4)°. There is an intra-molecular C-H⋯Cl hydrogen bond. In the crystal structure, the centroid-to-centroid distance between stacked fluorene ring systems is ca 4.22 Å, which indicates that there are no π-π stacking inter-actions between them.
