A simple, atom economical, fast and highly efficient green protocol has been developed for the synthesis of nitroamines and nitrosulfides by the Michael addition of amines and thiols to nitroolefins by simple mixing or grinding. This catalyst-free and solvent-free green approach provided the addition products in quantitative yield within minutes at room temperature. This procedure does not require any water quenches, solvent separations and purification steps such as recrystallization and column chromatography.
一种简单、原子经济、高效且快速的绿色方法已被开发,用于通过简单混合或研磨,将胺和硫醇与硝基烯烃进行迈克尔加成,从而合成硝基胺和硝基硫化物。这种无催化剂和无溶剂的绿色方法在室温下能够在几分钟内定量产出加成产物。该方法不需要任何水淬火、溶剂分离和重结晶、柱色谱等纯化步骤。
