2,5-Dichloro-1-(ROSO2)benzene [R=C6H5, C6F5, and CH2(CF2)4H]: Synthesis, molecular structure, and solubility in supercritical CO2

Crystal structure of phenyl 2,4,5-tri-chloro-benzene-sulfonate

The title compound, C12H7Cl3O3S, was synthesized via a nucleophilic substitution reaction between phenol and 2,4,5-tri-chloro-benzene-sulfonyl chloride. The two aryl rings are oriented gauche to one another around the sulfonate S-O bond, with a C-S-O-C torsion angle of -70.68 (16)°, and the two rings are inclined to one another by 72.40 (7)°. In the crystal, mol-ecules are linked via various C-Cl⋯π inter-actions, forming ribbons propagating along [100]. Neighboring ribbons are linked by a weak C-Cl⋯π inter-action, forming layers parallel to (010).
