DMSO, DMAc, and NMP in nucleophilic aromatic substitutionreactions (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。

nucleophilic aromatic subsitution (SNAr) reactions between various nucleophiles and electrophiles. The mild reactionconditions facilitate a broad functional group tolerance that can be utilized for subsequent derivatization for the synthesis of pharmaceutically relevant building blocks. The use of only equimolar amounts of all reagents and water as reaction solvent reveals the greenness and sustainability
