The f-block chemistry of phospholyl and arsolyl ligands, heavier p-block analogues of substituted cyclopentadienyls (Cp , C R ) where one or more CR groups are replaced by P or As atoms, is less developed than for lighter isoelectronic C R rings. Heterocyclopentadienyl complexes can exhibit properties that complement and contrast with Cp chemistry. Given that there has been renewed interest in phospholyl and arsolyl f-block chemistry in the last two decades, coinciding with a renaissance in f-block solution chemistry, a review of this field is timely. Here, the syntheses of all structurally characterised examples of lanthanide and actinide phospholyl and arsolyl complexes to date are covered, including benzannulated derivatives, and together with group 3 complexes for completeness. The physicochemical properties of these complexes are reviewed, with the intention of motivating further research in this field.
磷杂环戊二烯基和砷杂环戊二烯基配体的f区化学，即取代环戊二烯基（Cp、C₅R₅）的较重p区类似物（其中一个或多个CR基团被P或As原子取代），其发展程度不如较轻的等电子C₅R₅环。杂环戊二烯基配合物可展现出与Cp化学互补且形成对比的性质。鉴于在过去二十年中，人们对磷杂环戊二烯基和砷杂环戊二烯基f区化学重新产生了兴趣，这与f区溶液化学的复兴相契合，对该领域进行综述恰逢其时。本文涵盖了迄今为止所有结构已表征的镧系和锕系磷杂环戊二烯基及砷杂环戊二烯基配合物的合成实例，包括苯并稠合衍生物，为全面起见还包括第3族配合物。对这些配合物的物理化学性质进行了综述，旨在推动该领域的进一步研究。
