In the title compound, C21H22O2S, the cyclopentyl ring adopts an envelope conformation with the flap atom connected to the benzofuran residue. The benzofuran unit is essentially planar, with a mean deviation from the least-squares plane defined by the nine constituent ring atoms of 0.008 (2) Å. In the crystal, molecules are linked via pairs of C—Hπ interactions, forming inversion dimers. In the ring of the 4-methylphenyl group, four C atoms and their attached H atoms are disordered over two sets of sites, with site-ccupancy factors of 0.899 (5) and 0.10.

There are two symmetry-independent molecules, A and B, in the asymmetric unit of the title compound, C17H14FIO3S. The dihedral angle formed by the 4-fluorophenyl ring and the mean plane [r.m.s. deviation = 0.013 (2) Å in molecule A and 0.016 (2) Å in molecule B] of the benzofuran fragment is 57.71 (7)° in molecule A and 44.95 (7)° in molecule B. In the crystal, molecules are linked by weak C—HO hydrogen bonds and IO contacts [IO = 3.3646 (15) and 3.2354 (14) Å], forming a three--dimensional network.

In the title compound, C16H12BrFO3S, the 4-fluorophenyl ring makes a dihedral angle of 72.35 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, molecules are linked into [010] chains via two different inversion-generated pairs of C—HO hydrogen bonds. The crystal structure also exhibits slipped π–π interactions between the benzene rings of neighbouring molecules [centroid–centroid distance = 3.667 (2) Å and slippage = 1.341 (2) Å], and between the benzene and the furan rings of neighbouring molecules [centroid–centroid distance = 3.759 (2) Å and slippage = 0.757 (2) Å].

In the title compound, C20H12BrFO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.006 (2) Å] of the benzofuran fragment and the pendant 4-fluorophenyl and phenyl rings are 84.98 (5) and 40.98 (6)°, respectively. In the crystal, molecules are linked by C—HO and C—Hπ interactions.
