Cyclopentadienyliron dicarbonyl based allenyliron complexes were prepared, and their formal [3 + 2] cycloaddition with a number of dipolar reagents was investigated as a means of preparing heterocyclic compounds in a regiocontrolled manner. In addition, the mechanism of the isomerization of an allenyliron complex to its propargyliron tautomer was investigated. Results in support of both radical and
制备了基于环戊二烯基二羰基的丙二烯基配合物,并研究了它们与许多偶极试剂的正式 [3 + 2] 环加成反应,作为以区域控制方式制备杂环化合物的一种手段。此外,还研究了丙炔基配合物异构化为其炔丙基互变异构体的机理。提供了支持异构化的自由基和双电子机制的结果。
