Metal- and photocatalyst-free C3-H functionalization of quinoxalin-2(1H)-ones enabled by electron donor-acceptor complex photoactivation

A straightforward and metal- and photocatalyst-free method for the C3-arylation and alkylation of quinoxalin-2(1H)-ones has been developed. This protocol exploits the photoactivation of electron donor-acceptor (EDA) complexes between quinoxalinones and...
