The development of new versatile alkylation reagents that can be transformed from diverse available chemical raw materials is highly desirable. Here, an efficient, metal-free organic photoredox-catalyzed direct alkylation of heteroarenes via a desulphurization strategy using alkylsulfonium salts as alkylation reagents under mild conditions has been described for the first time. The inexpensive and efficient organic photoredox-catalyzed method offers a new and useful strategy for constructing various biologically interesting heteroarenes in the fields of synthetic and pharmaceutical chemistry, and extends the scope of the still limited sulfonium salt photochemistry.
