  • Cross-coupling processes without the use of transition metals are challenging to achieve. Here, the authors show a transition-metal-free cross-coupling utilizing aryl(heteroaryl) methyl sulfoxides and alcohols to afford alkyl aryl(heteroaryl) ethers and propose a nucleophilic addition mechanism based on experiments and theory.

  • Sulfilimines are a class of chiral molecules that bear S(IV) stereocentres, which are of high value in drug discovery but difficult to synthesize. Now the authors report a chemo- and enantioselective Chan–Lam S-arylation of sulfenamides with arylboronic acids that delivers diaryl and alkyl aryl sulfilimines.

  • Sulfenamides are a class of divalent sulfur-derived scaffolds featuring an S-N bond with many industrial applications, however, they are also challenging substrates for synthetic transformations. Here, the authors present a highly chemoselective ligand-controlled Chan–Lam coupling of sulfenamides as a straightforward route to N-arylated sulfenamides.

  • Cross coupling under transition-metal-free conditions is an attractive and economic alternative to traditional transition-metal-catalysed methods. Metal-free coupling of azaallyls has now been demonstrated with vinyl bromide electrophiles, delivering allylic amines in excellent yields. Moreover, mechanistic evidence supports dual reaction pathways triggered by azaallyl anions and radicals.
