DMSO, DMAc, and NMP in nucleophilic aromatic substitution reactions (SNAr), a simple and environmentally friendly alternative is reported. Use of a “benign-by-design” nonionic surfactant, TPGS-750-M, in water enables nitrogen, oxygen, and sulfur nucleophiles to participate in SNAr reactions. Aromatic and heteroaromatic substrates readily participate in this micellar catalysis, which takes place at or
鉴于对偶极的巨大依赖性,非质子溶剂如DMF,DMSO,DMAC,和NMP中的亲核芳族取代反应(S Ñ报道的Ar),一个简单的和环境友好的替代品。在水中使用“良性设计”非离子表面活性剂TPGS-750-M可使氮,氧和硫亲核试剂参与S N Ar反应。芳族和杂芳族底物容易参与这种胶束催化,该胶束催化在环境温度或环境温度附近发生。
