Cu‐catalyzed Bilateral Linkage of Sulfenamides for the Construction of Benzothiophene‐based Cyclic Sulfilimines
Abstract A CuI‐catalyzed bilateral linkage of S ‐phenethyl‐sulfenamides with cyclic diaryliodonium salts was developed for the one‐step construction of benzothiophene‐based cyclic sulfilimines. The challenging cyclic sulfoximines can be efficiently obtained via subsequent oxidation. Photophysical properties and DFT calculations reveal that cyclic sulfoximines, compared to cyclic sulfilimines and sulfones, exhibit larger Stokes shifts and reduced HOMO‐LUMO orbital overlap.
