N-[4-(2-Propyn-1-yloxy)phenyl]acetamide
The title compound, C(11)H(11)NO(2), was synthesized by chemoselective N-acetyl-ation of 4-amino-phenol followed by reaction with propargyl bromide in the presence of K(2)CO(3). the acetamide and propyn-1-yloxy substituents form dihedral angles of 18.31 (6) and 7.01 (10)°, respectively, with the benzene ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains along [010]....
متن کامل1-Nitro-4-(2-nitroprop-1-enyl)benzene
The asymmetric unit of the title compound, C(9)H(8)N(2)O(4), contains two crystallographically independent mol-ecules, both of which adopt an E configuration about the C=C bond. In the crystal, the mol-ecules stack into columns along the c axis through π-π inter-actions, with centroid-centroid distances of 3.695 (3) and 3.804 (3) Å. The columns are further connected into a three-dimensional net...
متن کامل(E)-1-Nitro-4-(2-nitroethenyl)benzene
The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), consists of two independent mol-ecules with similar geometries, each adopting a trans configuration about the olefinic double bond. The two mol-ecules are both almost planar (r.m.s. deviations = 0.034 and 0.035 Å) and form a dihedral angle of 83.62 (2)°. Short N⋯O contacts [2.834 (3)-2.861 (3) Å] are observed between the nitro groups ...

The title compound, C(25)H(24)ClNO(3), has three contiguous chiral centres. The absolute structure was determined by anomalous dispersion. The chloro-benzene ring is inclined to the two phenyl rings by 14.98 (9) and 59.05 (9)°. The two phenyl rings are inclined to one another by 49.51 (10)°. In the crystal, neighbouring mol-ecules are linked via C-H⋯O hydrogen bonds, forming chains propagating ...
