blocks: α‐Sulfenylated imines containing a quaternary center, an ubiquitous subunit and excellent building block, were achieved by rhodium‐catalyzed denitrogenative [2,3] sigmatropic rearrangements of N‐sulfonyl‐1,2,3‐triazoles with allylaryl(alkyl) sulfides. Coupling of this methodology with a copper‐catalyzed cycloaddition reaction provides a platform for the direct regioselective functionalization of

An example of a transition-metal-free, direct, and efficient acetamidosulphenylation reaction of alkenes using nitriles as the nucleophiles via a radical process is presented. This reaction shows a broad substrate scope and high regioselectivity and provides straightforward access to acetamidosulfide derivatives in moderate to high yields.
