Photocatalyst-, metal- and additive-free, direct C–H arylation of quinoxalin-2(1 H )-ones with aryl acyl peroxides induced by visible light
A visible light-mediated direct C–H arylation of quinoxalin-2(1 H )-ones with aryl acyl peroxides has been developed. The reaction proceeds smoothly through a radical process in the absence of photocatalyst, additive and metal catalyst, providing the corresponding products in moderate to good yields...
