摘要
A mild visible-light-induced Pd-catalyzed intermolecular radical cascade reaction of N- arylacrylamides with unactivated alkyl bromides is disclosed. Photoexcited Pd complexes transfer a single electron in this protocol, and hybrid alkyl Pd-radical species are involved as the key reaction intermediates. Sophisticated bioactive oxindole derivatives bearing various substituents and substitution patterns can be efficiently afforded through this approach.
