Crystal structure of 3-(2-bromophenylsulfonyl)-2,5,7-trimethyl-1-benzofuran
In the title compound, C17H15BrO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.016 (2) Å] and the 2-bromo-phenyl ring is 82.93 (6)°. In the crystal, mol-ecules are linked via pairs of C-H⋯π hydrogen bonds and π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.881 (2) Å] into inversion-r...

The crystal and molecular structures of the title compounds, ethyl 4-(4-hydroxyphenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (I) and ethyl 4-(3-bromophenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate (II), are reported and confirmed by single crystal X-ray diffraction data. Compound (I), C26H24O5, crystallizes from a methanol solution in the monoclinic C2/c ...
متن کاملCrystal structure of methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate.
A photochemical cycloaddition reaction of methyl 2-pyrone-5-carboxylate with methacrylonitrile mainly gave a [4 + 2] cycloadduct, assigned as methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate, whose structure was determined by an X-ray diffraction study. The formation of the cycloadduct was reasonably explained by considering a biradical intermediate having a les...
متن کاملCrystal structure of 3-(4-bromophenylsulfonyl)-2,5,6-trimethyl-1-benzofuran
In the title compound, C17H15BrO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.015 (2) Å] and the 4-bromo-phenyl ring is 89.29 (6)°. In the crystal, mol-ecules are linked into a chain along the b-axis direction by C-H⋯π hydrogen bonds and C-Br⋯π [3.626 (1) Å] inter-actions.
متن کاملCrystal structure of 5-bromo-2,4,6-trimethyl-3-[(2-methylphenyl)sulfinyl]-1-benzofuran
In the title compound, C18H17BrO2S, the dihedral angle between the mean planes of the benzo-furan [r.m.s. deviation = 0.025 (2) Å] and the 2-methyl-benzene rings is 87.87 (5)°. In the crystal, mol-ecules are linked into supra-molecular layers parallel to (0-11) by C-H⋯O hydrogen bonds and Br⋯Br [3.4521 (5) Å] contacts. These are connected into a three-dimensional architecture via C-H⋯π inter-ac...
