4-Acetyl-3-[2-(ethoxycarbonyl)phenyl]sydnone
Sydnones, which contain a mesoionic five-membered heterocyclic ring, are more stable if synthesized with an aromatic substutuent at the N3 position. In the title compound {sys-tematic name: 4-acetyl-3-[2-(eth-oxy-carbon-yl)phen-yl]-1,2,3-oxa-diazol-3-ylium-5-olate}, C13H12N2O5, the aromatic substitutent is 2-(eth-oxy-carbon-yl)phenyl. Intra- and inter-molecular hydrogen bonds are observed. The ...
متن کاملEthyl 2-acetyl-3-(4-bromoanilino)butanoate
The title compound, C(14)H(18)BrNO(3), adopts an extended conformation, with all of the main-chain torsion angles associated with the ester and amino groups close to trans. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds are observed.

The title compound, C(14)H(18)ClNO(3), adopts an extended conformation, with all of the main chain torsion angles associated with the ester and amino groups trans. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds are observed.
متن کامل1-Acetyl-3-(4-chlorophenyl)-5-(4-fluorophenyl)-2-pyrazoline
In the title mol-ecule, C(17)H(14)ClFN(2)O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chloro-benzene and 4-fluoro-benzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak inter-molecular C-H⋯O hydrogen bonds help stabilize the crystal structure.
متن کاملCrystal structures of 2-acetyl-4-ethynylphenol and 2-acetyl-4-(3-hydroxy-3-methylbut-1-yn-1-yl)phenol
In the title compounds, C10H8O2, (I), and C13H14O3, (II), the 2-acetyl-4-ethynylphenol unit displays a planar geometry, which is stabilized by an intra-molecular O-H⋯O hydrogen bond. The crystal structure of (I) is constructed of infinite strands, along [101], of C-H⋯O=C hydrogen-bonded mol-ecules, which in turn are linked by C-H⋯π inter-actions. In the crystal of (II), which crystallized with ...
