The Michael reaction of various nitroalkanes 1 with electrophilic alkenes 2 can be performed in NaOH (0.025−0.1 M), without any organic solvent. In many cases the presence of cetyltrimethylammonium chloride (CTACl), as cationic surfactant, produces better results. Good yields of the products 3 are obtained even with hindered, and functionalized starting materials.
各种硝基烷烃 1 与亲电烯烃 2 的迈克尔反应可以在 NaOH (0.025-0.1 M) 中进行,无需任何有机溶剂。在许多情况下,十六烷基三甲基氯化铵 (CTACl) 作为阳离子表面活性剂的存在会产生更好的结果。即使使用受阻和官能化的起始材料,也能获得良好的产物3产率。
