using a combination of the water-soluble radical initiator, 2,2′-azobis[2-(2-imidazolin-2-yl)propane] (VA-061), a water-soluble chain carrier, hypophosphorous acid, and the base, triethylamine, in aqueous alcohol is described. The reagents used in this method are all water soluble, and therefore, an almost pure desired product can be readily obtained using only an extraction procedure.
使用水溶性自由基引发剂,2,2'-偶氮双[2-(2-咪唑啉-2-基)丙烷](VA)的组合物,用于还原各种卤代化合物的简单,温和且高产的方法-061),描述了在含水醇中的水溶性链载体次磷酸和碱三乙胺。此方法中使用的试剂都是水溶性的,因此,仅使用萃取程序即可轻松获得几乎纯净的所需产品。
