3',4'-Dimeth­oxy­biphenyl-4-carbonitrile

The title compound, C₁₅H₁₃NO₂, was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the biphenyl rings is 40.96 (6)°. The meth­oxy groups are twisted slightly out of the plane of the benzene ring [C-C-C-C torsion angles = -3.61 (18) and 12.6 (2)°]. The packing of the molecules is stabilized by van der Waals inter­actions.

3,4-Dimeth­oxy-4'-nitro-1,1'-biphen­yl

The title compound, C₁₄H₁₃NO₄, was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The asymmetric unit comprises two mol­ecules related by pseudo-inversion symmetry. The dihedral angles between the benzene rings in the two mol­ecules are 44.30 (6) and 48.50 (6)° while those between the benzene ring and the nitro group are 6.54 (13) and 5.73 (10)°. The crystal packing is defined only by Van der Waals inter­actions.

3-(2-Chloro-3,3,3-trifluoro­prop-1-en-1-yl)-2,2-dimethyl-N-[3-(trifluoro­meth­yl)phen­yl]cyclo­propane­carboxamide

In the title mol­ecule, C₁₆H₁₄ClF₆NO, the cyclo­propane ring forms a dihedral angle of 70.82 (18)° with the benzene ring. The torsion angles about the ethyl­ene and amide bonds are −2.2 (5) (Cl—C—C—C) and 0.8 (5)° (O—C—N—C). A supra­molecular chain propagated by glide symmetry along [001] and mediated by N—H...O hydrogen bonds is observed in the crystal packing.
