aggregate−H2O interfaces to control the regioselectivity of Diels−Alder reactions has been investigated. Cycloadditions of surfactant 1,3-dienes 2-[[3-(dimethyldodecylsilyl)-1,3-butadien-2-yl]thio]-N,N,N-trimethyl-1-ethanaminium iodide (1a) and 6-[[3-(dimethyloctylsilyl)-1,3-butadien-2-yl]thio]-N,N,N-trimethyl-1-hexanaminium iodide (1b) with surfactant dienophiles (E)-2-[[[2-(dodecoxycarbonyl)ethenyl]carbonyl]oxy]-N
已经研究了表面活性剂聚集体-H2O 界面控制 Diels-Alder 反应区域选择性的能力。表面活性剂 1,3-二烯 2-[[3-(二甲基十二烷基甲硅烷基)-1,3-butadien-2-yl]thio]-N,N,N-trimethyl-1-ethanaminium iodide (1a) 和 6-[ [3-(二甲基辛基甲硅烷基)-1,3-丁二烯-2-基]硫代]-N,N,N-trimethyl-1-hexanaminium iodide (1b) 与表面活性剂亲二烯体 (E)-2-[[[2-(十二氧羰基)乙烯基]羰基]氧基]-N,N,N-三甲基-1-乙胺碘化物(2a)和(E)-6-[[[2-(辛氧羰基)乙烯基]羰基]氧基]-N,N, N-trimethyl-1-hexanaminium bromide (2b) 在其水性混合胶束中已在 25(35) °C 下进行。1a 和 2a 的环加成得到
