π-Allylpalladium intermediates are known to participate efficiently in transformations involving nucleophilic species. Exploring these processes, we have developed a method for the preparation of allyl acetates via palladium-catalysed functionalisation of allenes and 1,3-dienes. Reactions of aryl iodides with either of these two classes of compounds and excess sodium acetate in the presence of Pd(OAc)2
已知π-烯丙基钯中间体可有效地参与涉及亲核物质的转化。探索这些过程,我们已经开发了一种通过钯催化的丙二烯和1,3-二烯官能化反应制备乙酸烯丙酯的方法。在作为催化体系的Pd(OAc)2和Ph 3 P存在下,芳基碘化物与这两类化合物中的任一种和过量的乙酸钠反应,得到各自的乙酸烯丙酯,产率中等至良好。已经研究了该过程的范围。所描述的方法是用于制备乙酸烯丙酯的合成库的补充,并且尤其可用于合成这种类型的结构复杂的化合物。 乙酸烯丙酯-钯催化-丙二烯-二烯-合成
