(E)-4-(4-Methoxyphenyl)but-3-en-2-one
In the title compound, C(11)H(12)O(2), the dihedral angle between the benzene ring and the but-3-en-2-one group is 4.04 (5)°. The crystal packing features chains, parallel to [-101], composed of dimers connected by weak C-H⋯O inter-actions..
متن کامل4-(2,6-Dibromo-4-fluoroanilino)pent-3-en-2-one
The title enamino-ketone, C(11)H(10)Br(2)FNO, has a roughly planar pentenone chain; the maximum displacement of an atom from the pentenone plane is 0.071 (4) Å. The dihedral angle between the benzene ring and the pentenone unit is 77.2 (1)°. Inter-molecular C-H⋯Br and C-H⋯O inter-actions, as well as an intra-molecular N-H⋯O inter-action, are observed. In both methyl groups, each H atom is disor...
متن کامل4-[(4-Methylphenyl)amino]pent-3-en-2-one
The title enamino-ketone, C(12)H(15)NO, is a derivative of 4-(phenyl-amino)-pent-3-en-2-one with an approximately planar pentenone backbone, the greatest displacement from the plane being 0.042 (1) Å; the asymmetry in C-C distances in the group suggests the presence of unsaturated bonds. The dihedral angle between the benzene ring and the pentenone plane is 29.90 (4)°. In the crystal, an intra-...
متن کامل4-(3-Nitrophenyl)-3-(phenylsulfonyl)but-3-en-2-one
The C=C double bond in the title mol-ecule, C(16)H(13)NO(5)S, has an E configuration. The crystal structure is stabilized by C-H⋯O hydrogen bonds. There is also a weak C-H⋯π-ring inter-action in the structure.
متن کامل(S)-3-[(S,E)-4-(4-Chlorophenyl)-1-nitrobut-3-en-2-yl]thian-4-one
The title compound, C(15)H(16)ClNO(3)S, was obtained by the organocatalytic asymmetric Michael addition of thian-4-one to 1-chloro-4-[(1E,3E)-4-nitro-buta-1,3-dien-yl]benzene. The double bond has an E configuration and the thian-4-one six-membered ring adopts a chair conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
