2-(4-Fluoro-phen-yl)-1-(phenyl-sulfin-yl)-naphtho-[2,1-b]furan.

ABSTRACT: In the title compound, C(24)H(15)FO(2)S, the 4-fluoro-phenyl ring makes a dihedral angle of 19.43?(4)° with the mean plane of the naphtho-furan fragment. The dihedral angle between the phenyl ring and the mean plane of the naphtho-furan fragment is 85.83?(4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H?O hydrogen bonds.

Project description:In the title compound, C(24)H(15)BrO(2)S, the sulfinyl O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane through the naphthofuran fragment. The phenyl ring is nearly perpendicular to the plane of the tricyclic naphthofuran system [81.77?(6)°] and is tilted slightly towards it. The 4-bromo-phenyl ring is rotated out of the naphthofuran plane by a dihedral angle of 31.12?(4)°. In the crystal structure, non-classical inter-molecular C-H?O and C-H?Br hydrogen bonds are observed. The crystal structure also exhibits aromatic ?-? inter-actions between the furan ring and the central benzene ring of the adjacent naphthofuran system [centroid-centroid distance = 3.768?(3)?Å]. In addition, inter-molecular C-Br?? inter-actions [3.866?(2)?Å] between the Br atom and the phenyl ring of the phenyl-sulfinyl substituent are present.

7-Bromo-2-phenyl-1-(phenyl-sulfin-yl)naphtho[2,1-b]furan benzene hemisolvate.

Project description:The title compound, C(24)H(15)BrO(2)S·0.5C(6)H(6), crystallizes as a benzene hemisolvate. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the naphthofuran fragment, and the phenyl ring is almost perpendicular to the plane of the naphthofuran fragment [83.78?(8)°] and is tilted slightly towards it. The 2-phenyl ring is rotated out of the naphthofuran plane by a dihedral angle of 25.2?(1)°. The crystal structure is stabilized by aromatic ?-? inter-actions between the central benzene ring and the furan ring of the neighbouring naphthofuran systems [centroid-centroid distance = 3.611?(3)?Å], and by inter-molecular C-H?? inter-actions between the benzene H atom of the phenyl-sulfinyl substituent and the 2-phenyl ring of an adjacent mol-ecule. In addition, the crystal structure exhibits a weak non-classical inter-molecular C-H?O hydrogen bond.
