organic compounds
The title compound, C20H19BrO2S, was synthesized by the cyclization of 1-(4-bromophenyl)-4-(3,4-dimethoxyphenyl)-2,3-dimethylbutane-1,4-dione with 2,4-bis(4-methoxyphenyl)-2,4-disulfanylene-1,3,2,4-dithiadiphosphetane. The dimethoxyphenyl and bromophenyl rings make dihedral angles of 28.4 (3) and 45.0 (3)°, respectively, with the thiophene ring. The bond lengths are unexceptional.
