C3-H functionalization occurs with improved efficiency in quinoxalinones, yet remains metal-free and photocatalyst-free.
The technique employs photoactivation using electron donor-acceptor complexes to drive the reaction effectively.
The approach streamlines the process for C3-arylation and alkylation of quinoxalinones, enriching synthetic methodologies.
The findings highlight potential applications in organic synthesis, supporting greener alternatives across various sectors.

Implication

This method demonstrates C3-H functionalization in quinoxalinones, suggesting efficient synthesis without metals or photocatalysts.

Abstract

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...
