Sulfur(IV) in Transition-Metal-Free Cross-Couplings for Biaryl Synthesis
Gregory J. P. Perry, Hideki Yorimitsu
Abstract
The reactivity of sulfur(IV) compounds is of great current interest among organic chemists. In this Perspective, we discuss the chemistry of sulfur(IV) (namely, sulfoxides, sulfonium salts, and sulfinates) within the area of transition-metal-free cross-couplings for biaryl synthesis. These sulfur(IV)-based methods show potential in sustainable biaryl formation and can deliver unique biaryl structures that are difficult to access by other means. This Perspective also highlights how the versatile reactivity of sulfur(IV) has helped design new reagents, mediators, and catalysts.
