5-Bromo-3-cyclo-hexyl-sulfinyl-2,4,6-trimethyl-1-benzo-furan.

ABSTRACT: In the title compound, C17H21BrO2S, the cyclo-hexyl ring adopts a chair conformation and the aryl-sulfinyl unit is positioned equatorially relative to the cyclo-hexyl group. The benzo-furan unit is essentially planar, with an r.m.s. deviation of 0.016?(2)?Å. In the crystal, mol-ecules are linked by weak C-H?O, C-H?? and Br?? [3.663?(2)?Å] inter-actions, resulting in a three-dimensional network. A Br?Br [3.6838?(6)?Å] contact is observed. The O atom of the sulfinyl group is disordered over two orientations with an occupancy ratio of 0.863?(5):0.137?(5).

5-Cyclo-hexyl-2-(2-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzo-furan.

Project description:In the title compound, C21H21FO2S, the cyclo-hexyl ring adopts a chair conformation.

2,5,7-Trimethyl-3-phenyl-sulfinyl-1-benzo-furan.

Project description:The title compound, C(17)H(16)O(2)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is nearly perpendicular to the plane of the benzofuran unit [88.30?(9)°] and is tilted slightly towards it. No ?-? or C-H?? inter-actions are observed between neighbouring mol-ecules in the crystal structure because of steric hindrance induced by the three methyl groups.

3-(2-Bromo-phenyl-sulfon-yl)-5-cyclo-hexyl-2-methyl-1-benzo-furan.

Project description:In the title compound, C21H21BrO3S, the cyclo-hexyl ring adopts a chair conformation.

Inter-molecular C-H?O hydrogen bonds and short Br?O [3.280?(1)?Å] contacts further consolidate the crystal packing.
