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 simple and products can be easily isolated with good to high yields.
