Abstract: A photoredox-catalysed chlorination of quinoxalin-2(1H)-ones was developed by using CHCl3 as a chlorine source, thus affording various 3-chloroquinoxalin-2(1H)-ones in moderate to high yields. This protocol is characterized by mild reaction conditions, excellent regioselectivity, and readily… read more here.
