| Abstract: | A wide variety of secondary amines are chemoselectively subjected to N-nitrosation reaction with treatment of citric acid and NaNO2 in the presence of wet SiO2(50%,w/w)in dichloromethane at room temperatture under heterogeneous conditions.The N-nitrosation method is very simle and products can be easily isolated with good to high yields. |
| Keywords: | N-Nitrosation Secondary amines Heterogeneous Citric acid NANO2 |
