Abstract
There are two independent molecules, A and B, in the asymmetric unit of the title compound, C15H17ClO2S, in each of which the cyclohexyl ring adopts a chair conformation. The benzofuran units in each molecule are essentially planar, with mean deviations from a least-squares plane defined by the nine constituent ring atoms of 0.006 (2) Å for A and 0.011 (2) Å for B. In the crystal, molecules are linked by weak intermolecular C—H⋯O and C—H⋯π interactions and by two I⋯O contacts [I⋯O = 3.079 (2) and 3.017 (2) Å].

There are two independent molecules, A and B, in the asymmetric unit of the title compound, C15H17ClO2S, in each of which the cyclohexyl ring adopts a chair conformation
As a part of our ongoing study of the substituent effect on the solid state structures of 3-cyclohexylsulfinyl-5halo-2-methyl-1-benzofuran analogues (Choi et al, 2011), we report on the molecular and crystal structures of the title compound
In the crystal packing (Fig. 2), the B molecules are linked by weak intermolecular C—H···O hydrogen bonds between a methyl H atom and the O atom of the S═O unit (Table 1; C24—H24A···O4i), and by intermolecular C—H···π interactions between a cyclohexyl H atom and the furan ring
