Visible-light-induced mesoporous graphitic carbon nitride-catalyzed trifluoromethylation and perfluoroalkylation of 4-aminocoumarins

Abstract

A heterogeneous mesoporous graphitic carbon nitride (mpg-C 3 N 4 ) photocatalytic 3-trifluoromethylation/perfluoroalkylation of 4-aminocoumarins was realized from 4-aminocoumarins and C n F 2 n +1 SO 2 Na under mild conditions.
