5-Bromo-2,7-dimethyl-3-(4-methyl­phenyl­sulfin­yl)-1-benzo­furan

In the title compound, C₁₇H₁₅BrO₂S, the 4-methyl­benzene ring makes a dihedral angle of 89.01 (7)° with the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzo­furan fragment. In the crystal, mol­ecules are linked into supra­molecular layers that stack along [001] by weak C—H...O, C—H...π and C—S...π [3.364 (2) Å] inter­actions.

2-(2-Fluoro­phen­yl)-3-methyl­sulfanyl-5-phenyl-1-benzo­furan

In the title compound, C₂₁H₁₅FOS, the dihedral angles between the mean plane [r.m.s. deviation = 0.041 (1) Å] of the benzo­furan fragment and the pendant 2-fluoro­phenyl and phenyl rings are 46.09 (3) and 24.34 (5)°, respectively. In the crystal, mol­ecules are linked by weak C—H...π inter­actions, forming a three-dimensional network.

3-(4-Bromo­phenyl­sulfin­yl)-5-chloro-2,7-dimethyl-1-benzo­furan

In the title compound, C₁₆H₁₂BrClO₂S, the 4-bromo­phenyl ring makes a dihedral angle of 88.84 (5)° with the mean plane [r.m.s. deviation = 0.009 (1) Å] of the benzo­furan fragment. In the crystal, mol­ecules are linked by weak C—H...O and C—S...π [3.386 (2) Å] inter­actions, forming a chain perpendicular to the bc plane.

5-Bromo-2-(2-fluoro­phen­yl)-3-methyl­sulfinyl-1-benzo­furan

In the title compound, C₁₅H₁₀BrFO₂S, the 2-fluoro­phenyl ring makes a dihedral angle of 32.28 (6)° with the mean plane [r.m.s. deviation = 0.010 (1) Å] of the benzo­furan fragment. In the crystal, mol­ecules are linked by weak C—H...O hydrogen bonds and Br...O contacts [3.0917 (13) Å], forming a three-dimensional network.

2,5-Dimethyl-3-(4-methyl­phenyl­sulfon­yl)-1-benzo­furan

In the title compound, C₁₇H₁₆O₃S, the dihedral angle between the 4-methyl­phenyl ring and the mean plane [r.m.s. deviation = 0.011 (1) Å] of the benzo­furan ring system is 71.47 (5)°. In the crystal, mol­ecules are linked by weak C—H...O hydrogen bonds, and by slipped π–π inter­actions between the benzo­furan ring systems of neighbouring mol­ecules [centroid–centroid distances = 3.638 (2) and 3.766 (2) Å, inter­planar distances = 3.564 (2) and 3.454 (2) Å, and slippages = 0.730 (2) and 1.501 (2) Å], forming a three-dimensional network.
