variety of secondary amines to the corresponding N-nitroso compounds under mild, heterogeneous conditions (Table). The process has several advantages: the reagents are inexpensive and non-hazardous, the reaction is clean, fast, and high-yielding, and MSA can be readily removed by filtration and re-used (after treatment with HCl) without loss of activity. Further, only N-nitrosation was observed, but no
湿钼酸硫酸(=二氧[双(sulfato- κO)]钼; MSA),一个新的固体酸,可与亚硝酸钠(纳米组合使用2)的各种仲胺转化成相应的Ñ亚硝基化合物在温和的非均质条件下(表)。该方法具有几个优点:该试剂便宜且无害,该反应清洁,快速且产率高,并且MSA可以容易地通过过滤除去并重新使用(在用HCl处理后)而不会损失活性。此外,仅观察到N-亚硝化,而没有观察到C-或O-亚硝化。
