Abstract A highly efficient green process for the synthesis of N,N′-disubstituted aliphatic thiourea derivatives using primary aliphatic amines and carbon disulfide in aqueous medium at room temperature via a nonisothiocyanate route is described. This protocol illustrates the rapid preparation of N,N′-disubstituted aliphatic thiourea derivatives in excellent yields with some advantages such as no catalyst
摘要 描述了一种在室温下,在水性介质中,通过非异硫氰酸酯路线,使用脂肪伯胺和二硫化碳合成 N,N'-二取代脂肪族硫脲衍生物的高效绿色工艺。该协议说明了以优异的收率快速制备 N,N'-二取代脂肪族硫脲衍生物, 具有一些优点, 如无催化剂和简单的后处理, 没有任何副产物形成。此外,新路线简洁,无需色谱,适用于中试制备。图形概要
