intramolecular freeradical [1,5]-ipso-substitution using sulfonamide and sulfonate derived tethering chains. The overall efficiency of the process is determined by appropriately positioned substituents on the aromatic acceptor ring. The extension of the process to benzylic sulfonates and their corresponding N-methylsulfonamide alternatives as substrates in potential [1,6]-ipso-substitution reactions leads
A palladium-catalyzed chelation-assisted C–H olefination of 2-amino biaryls using readily available vinylsilanes as unactivated alkenes was developed to afford valuable arylated vinylsilanes with exclusive (E)-selectivities.
