π-Allylic palladium complexes reacted with conjugated dienes to give diene-inserted products. Isoprene gave l,l-disubstituted allyl complexes rather than 1,2-disubstituted ones. Two types of allylic complexes were studied, and halogen-bridged dimer complexes showed lower reactivity than acetylacetonato complexes. When the allylic group or diene was varied, the reactivity decreased in the order: allyl
π-烯丙基钯配合物与共轭二烯反应生成二烯插入的产物。异戊二烯得到1,1-二取代的烯丙基络合物,而不是1,2-二取代的烯丙基络合物。研究了两种类型的烯丙基配合物,并且卤素桥联的二聚体配合物显示出比乙酰丙酮酮配合物低的反应性。当烯丙基或二烯变化时,反应性依次降低:烯丙基> 2-甲基烯丙基> 1-甲基烯丙基>肉桂基和丁二烯>异戊二烯>氯丁二烯> 2,3-二甲基丁二烯巴豆基络合物不易与丁二烯反应,得到主要具有以下结构的产品:讨论了反应性的变化和反应机理。
