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 Nnitrosation method is very simple and products can be easily isolated with good to high yields.
