Abstract

Abstract : A heterogeneous mesoporous graphitic carbon nitride (mpg-C3 N4 ) photocatalytic 3-trifluoromethylation/perfluoroalkylation of 4-aminocoumarins was realized from 4-aminocoumarins and C n F2 n +1 SO2 Na under mild conditions. Abstract : A heterogeneous photocatalytic 3-trifluoromethylation and 3-perfluoroalkylation of 4-aminocoumarins was realized from 4-aminocoumarins and C n F2 n +1 SO2 Na under mild conditions using mesoporous graphitic carbon nitride (mpg-C3 N4 ) as an effective and recyclable photocatalyst without any other additives. This transition-metal-free procedure shows wide substrate scope with air as a green oxidant affording 3-trifluoromethylated/perfluoroalkylated 4-aminocoumarins in moderate to good yields.
