In the title compound, C(14)H(15)BrO(4)S, the S atom has a distorted trigonal-pyramidal coordination. The O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The mol-ecules form slightly slipped π-stacked inversion-symmetric dimers by inter-molecular aromatic π-π inter-actions, with a(More)
In the title compound, C(15)H(17)BrO(4)S, the methyl-sulfinyl O atom and the methyl substituents lie on opposite sides of the plane through the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.698 (4) Å], and by C-H⋯π inter-actions between a(More)
The title compound, C(15)H(18)O(4)S, was prepared by the oxidation of isopropyl 2-(5-methyl-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The crystal structure is stabilized by inter-molecular π-π inter-actions between the benzene rings; the centroid-centroid distance between the adjacent benzene rings (symmetry code: ) is(More)
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(More)
The title compound, C(13)H(14)O(4)S, was prepared by oxidation of methyl 2-(5-methyl-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The O atom and methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran system. The crystal structure is stabilized by inter-molecular aromatic π-π(More)
The title compound, C(18)H(16)O(3)S, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The phenyl rings are rotated out of the benzofuran planes, making dihedral angles of 43.38 (7) and 56.13 (6)° in the two mol-ecules. The carboxyl groups are involved in inversion-related inter-molecular O-H⋯O hydrogen bonds, which link the(More)
The title compound, C(14)H(15)BrO(4)S, was prepared by the oxidation of ethyl 2-(5-bromo-3-ethyl-sulfanyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The crystal structure is stabilized by aromatic π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.814 (9) Å], and possibly by weak C-H⋯π(More)
In the title compound, C(13)H(12)BrClO(4)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. There is a mean deviation of 0.016 (4) Å from the least-squares plane defined by the nine constituent benzofuran atoms. The crystal structure is stabilized by aromatic π-π inter-actions(More)
The title compound, C(11)H(9)BrO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-bromo-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal structure, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further packed into stacks along the c axis by(More)
