used groups in organic synthesis. Here, a a series of thianthreniumsalts have been synthesized that act as reliable alkylation reagents and readily engage in copper-catalyzed Sonogashira reactions to build C(sp3)−C(sp) bonds under mild photochemical conditions. Diverse alkyl thianthreniumsalts, including methyl and disubstituted thianthreniumsalts, are employed with great functional breadth, since
