Potassium fluoride impregnated on natural zeolite as a new solid base system effectively catalyzes the coupling
of thiophenols with electron-deficient fluoro-, chloro- and bromo-arenes in DMSO. This versatile and efficient solid base
has been demonstrated to afford the corresponding desired products in good to excellent yields. This procedure provides a
convenient, efficient and practical method for the preparation of diaryl thioethers.
