[reaction: see text]. The combination of water-soluble radical initiator 2,2'-azobis[2-(2-imidazolin-2-yl)propane] (VA-061), water-soluble chain carrier 1-ethylpiperidine hypophosphite (EPHP), and surfactant cetyltrimethylammonium bromide (CTAB) was found to be the most suitable condition for effective radical cyclization in water for a variety of hydrophobic substrates.
[反应:见正文]。发现水溶性自由基引发剂2,2'-偶氮双2-(2-咪唑啉-2-基)丙烷、水溶性链载体次磷酸1-乙基哌啶盐(EPHP)和表面活性剂十六烷基三甲基溴化铵(CTAB)的组合是在水中对多种疏水底物进行有效自由基环化的最合适条件。
