Abstract: The palladium-catalysed dehydrogenation of sp3 carbon-hydrogen bonds of N- alkylbenzenesulfonamides allows a simple access to N-alkenylbenzenesulfonamides. The reaction proceeds with easily accessible catalysts, with pivalate as a base, and allows a variety of substituents both on nitrogen and on the arene moiety. Keywords: aryl halides; atom economy; CÀH bond functionalisation; dehydrogenation; palladium
