Arenediazonium o-benzenedisulfonimides can be used as new and efficient reagents for Heck-type arylation reactions of some common substrates containing C–C multiple bonds, namely ethyl acrylate, acrylic acid, acroleyne, styrene and cyclopentene. The reactions were carried out in an organic solvent, in the presence of Pd(OAc)2 as pre-catalyst, and gave rise to arylated products, for example, ethyl cinnamates

酰亚胺可用作一些常见的含C-C多键底物,即
丙烯酸乙酯,
丙烯酸,
丙烯醛,
苯乙烯和
环戊烯的Heck型芳基化反应的新型高效试剂。反应在有机溶剂中,在作为前催化剂的Pd(OAc)2存在下进行,并产生芳基化产物,例如
肉桂酸乙酯,
肉桂酸,
肉桂醛和
对苯二甲酸酯,具有(E) -构型和1-芳基
环戊烯,收率良好至优异。值得注意的是,所有反应导致以大于80%的产率回收邻苯二磺
酰亚胺,该邻苯二磺
酰亚胺可再循环用于制备其他重氮盐。
