3-(3-ChloroÂphenylÂsulfonÂyl)-2,5,7-trimethyl-1-benzofuran
In the title compound, C17H15ClO3S, the 3-chloroÂphenyl ring makes a dihedral angle of 77.76 (6)° with the mean plane [r.m.s. deviation = 0.007 (1) Å] of the benzofuran fragment. In the crystal, molÂecules are linked by weak interÂmolecular C—H⋯O and C—H⋯π interÂactions
2-(5-Fluoro-3-isopropylÂsulfanyl-7-methyl-1-benzofuran-2-yl)acetic acid
The title compound, C14H15FO3S, was prepared by alkaline hydrolysis of ethyl 2-(5-fluoro-3-isopropylÂsulfanyl-7-methyl-1-benzofuran-2-yl)acetate. In the crystal, molÂecules are linked via pairs of O—H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by weak C—H⋯O hydrogen bonds
1-(4-BromoÂphenylÂsulfinÂyl)-2-methylÂnaphthoÂ[2,1-b]furan
In the title compound, C19H13BrO2S, the 4-bromoÂphenyl ring makes a dihedral angle of 83.75 (4)° with the mean plane of the naphthoÂfuran fragment [r.m.s. deviation = 0.024 (2) Å]. In the crystal, molÂecules are linked via pairs of C—H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by weak π–π interÂactions between the central naphthoÂfuran benzene rings of neighbouring molÂecules [centroid–centroid distance = 3.483 (2) Å, interÂplanar distance = 3.416 (2) Å and slippage = 0.680 (2) Å]

In the title compound, C20H16O2S, the 4-methylÂphenyl ring makes a dihedral angle of 82.60 (4)° with the mean plane [r.m.s. deviation = 0.007 (1) Å] of the naphthoÂfuran fragment. In the crystal, molÂecules are linked by weak interÂmolecular C—H⋯O hydrogen bonds, and by a slipped π–π interÂaction between the central naphthoÂfuran benzene rings of neighbouring molÂecules [centroid-to-centroid distance = 3.671 (2) Å, interÂplanar distance = 3.349 (2) Å and slippage = 1.503 (2)°]
3-(4-BromoÂphenylÂsulfinÂyl)-2,5,7-trimethyl-1-benzofuran
In the title compound, C17H15BrO2S, the 4-bromoÂphenyl ring makes a dihedral angle of 87.78 (5)° with the mean plane of the benzofuran fragment. In the crystal, molÂecules are linked by weak C—H⋯O hydrogen bonds, and by weak interÂmolecular C—S⋯π [3.399 (2) Å] and C—Br⋯π [3.797 (2) and 3.757 (2) Å] interÂactions
5-CycloÂhexyl-2-methyl-3-(4-methylÂphenylÂsulfinÂyl)-1-benzofuran
In the title compound, C22H24O2S, the cycloÂhexyl ring adopts a chair conformation. The 4-methylÂphenyl ring makes a dihedral angle of 81.60 (5)° with the mean plane [r.m.s. deviation = 0.004 (1) Å] of the benzofuran fragment. In the crystal, molÂecules are linked by weak C—H⋯O hydrogen bonds and weak π–π interÂactions between the furan rings of adjacent molÂecules [centroid–centroid distance = 3.545 (2) Å, interÂplanar distance = 3.489 (2) Å and slippage = 0.628 (2) Å
2-(5,7-Dimethyl-3-methylÂsulfanyl-1-benzofuran-2-yl)acetic acid
The title compound, C13H14O3S, was prepared by alkaline hydrolysis of ethyl 2-(5,7-dimethyl-3-methylÂsulfanyl-1-benzofuran-2-yl)acetate. In the crystal structure, the carboxyl groups are involved in interÂmolecular O—H⋯O hydrogen bonds, which link the molÂecules into centrosymmetric dimers. These dimers are further packed into stacks along the a axis by weak C—H⋯π interÂactions
