It is shown that the cyclopentadienide anion can undergo an electrophilic substitution. In methylation reactions it was possible to stop the reaction at the intermediate 5-substituted cyclopentadiene stage. In the methylcyclopentadienide anion, the methyl group directs an electrophile to the adjacent carbon atom.
结果表明,环戊二烯阴离子可以进行亲电取代。在甲基化反应中,可以在中间的5-取代的环戊二烯阶段终止反应。在甲基环戊二烯阴离子中,甲基将亲电子体引导至相邻的碳原子。
