The sodiation of substituted acrylonitriles and alkenyl sulfides in a continuous flow set‐up using NaDA (sodium diisopropylamide) in EtNMe2 or NaTMP (sodium 2,2,6,6‐tetramethylpiperidide)⋅TMEDA in n‐hexane provides sodiated acrylonitriles and alkenyl sulfides, which are subsequently trapped in batch with various electrophiles such as aldehydes, ketones, disulfides and allylic bromides affording functionalized
使用 EtNMe 2中的 NaDA(二异丙基酰胺钠)或正己烷中的 NaTMP(2,2,6,6-四甲基哌啶钠)·TMEDA 在连续流装置中对取代的丙烯腈和烯基硫醚进行钠化,得到钠化的丙烯腈和烯基硫醚,随后与各种亲电子试剂(例如醛、酮、二硫化物和烯丙基溴)分批捕获,得到官能化的丙烯腈和烯基硫醚。通过使用巴比耶型条件,该流程已成功扩展到其他丙烯酸酯。
