Sonogashira reactions, a transition-metal-free version of the arylation of terminal alkynes is elusive. Herein, we report an efficient transition-metal-free Sonogashira-typecoupling reaction for the one-pot arylation of alkynes to construct C(sp)–C(sp2) bonds from a tetracoordinate boron intermediate with NIS as a mediator. With its high efficiency, wide substrate range, and good functional group tolerance
An effective one‐pot approach has been devised for the selective synthesis of alkynyl sulfides through the cleavage of C−S bonds in alkynyl sulfonium salts. This method involves a base‐promoted nucleophilic ring‐opening and desulfurization pathway, enabling the efficient preparation of diverse alkynyl sulfide compounds. The reaction demonstrates excellent tolerance to various functional groups and
