Abstract Efficient N‐nitrosation of amines, amides, and ureas, and also S‐nitrosation of thiols were performed with dinitrogen tetroxide impregnated on activated charcoal (N2O4/charcoal) in CH2Cl2 at room temperature. High selectivity was observed for N‐nitrosation of dialkyl amines, N‐alkylamides and N‐alkylureas. Dealkylation and N‐nitrosation of trialkylamines were also performed by this reagent
摘要 胺、酰胺和尿素的有效 N-亚硝化以及硫醇的 S-亚硝化在室温下用四氧化二氮浸渍在 CH2Cl2 中的活性炭(N2O4/木炭)上进行。观察到二烷基胺、N-烷基酰胺和 N-烷基脲的 N-亚硝化具有高选择性。三烷基胺的脱烷基化和 N-亚硝化也由该试剂进行。
