KF/clinoptilolite: An efficient promoter for the synthesis of thioethers

Salmanpour, Sadegh,Khalilzadeh, Mohammad A.,Hosseini, Abolfazl

, p. 339 - 344 (2013/07/28)

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.
