Wang, Jiayang; Sun, Bin; Zhang, Liang; Xu, Tengwei; Xie, Yuanyuan; Jin, Can published the artcile< Visible-light-induced trifluoromethylation of quinoxalin-2(1H)-ones under photocatalyst-free conditions>, Synthetic Route of 89898-96-4, the main research area is trifluoromethylquinoxalinone regioselective green preparation; quinoxalinone sodium trifluoromethanesulfinate trifluoromethylation.
C-H trifluoromethylation of quinoxalin-2(1H)-ones with com. available sodium trifluoromethanesulfinate (CF3SO2Na) under visible light irradiation without any external photocatalyst was developed, provided a variety of 3-trifluoromethylquinoxalin-2(1H)-ones I [R1 = H, 6-MeO, 7-Br, etc.; R2 = H, Me, Bn, etc.] in moderate to excellent yield. Predictably, the strategy would offer an environmentally friendly and simple operational access to pharmaceutically active 3-trifluoromethylquinoxalin-2(1H)-ones without any external photocatalyst.
Asian Journal of Organic Chemistry published new progress about Green chemistry. 89898-96-4 belongs to class quinoxaline, and the molecular formula is C8H5N3O3, Synthetic Route of 89898-96-4.
