A one-pot procedure for the synthesis of thienyl thioethers is described. Several thienyl thioethers were synthesized by a TfOH-promoted Friedel–Crafts-type cyclization, a subsequent nucleophilic attack by an arenethiol, and dehydration. This protocol was successfully applied to the synthesis of thienoacene derivatives by using a Pd-catalyzed dehydrogenative cyclization.
描述了一种用于合成噻吩硫醚的一锅法。通过TfOH促进的Friedel-Crafts型环化反应、随后的芳基硫醇亲核攻击和脱水反应,合成了几种噻吩硫醚。该方案成功应用于通过Pd催化的脱氢环化合成噻吩芳香烃衍生物。
