(VA-044) and the surfactant, cetyltrimethyl-ammonium bromide (CTAB), was found to be the most suitable condition for the effective and direct synthesis of useful active thioesters (pentafluorophenyl thioesters) in water. In addition, the direct amidation of aldehydes was achieved by the addition of the amines to the thioesterification reaction mixture in water.
发现了水溶性自由基引发剂2,2'-偶氮双[2-(2-咪唑啉-2-基)丙烷]二盐酸盐(VA-044)和表面活性剂十六烷基三甲基溴化铵(CTAB)的组合是在水中有效和直接合成有用的活性硫代酯(五氟苯基硫代酯)的最合适条件。另外,通过将胺加到水中的硫酯化反应混合物中来实现醛的直接酰胺化。
