摘要
封面上是一个圆底烧瓶，里面装着酒红色的二茂铁基磷离子[Fc2P][B(C6F5)4]溶液，在这项工作中用于激活各种烯。2-（三甲基硅基）- 5 -2,3-二烯滴加得到一种稳定的二茂铁惠兰中间体的亮红色溶液，其固态结构被描述为球棒模型。前面是圣彼得之钥，这是不来梅市徽的一个突出特征，代表着高度活跃的主要群体物种的未被释放的潜力。更多信息可以在E. Hupf， J. Beckmann及其同事的研究文章中找到（DOI: 10.1002/ eur.202500031）。
Front Cover: Activation of Allenes by Diferrocenylphosphenium Ion: Isolation of a Wheland Intermediate of Ferrocene (ChemistryEurope 5/2025)
The Front Cover shows a round-bottomed flask containing a burgundy solution of diferrocenylphosphenium ion [Fc2P][B(C6F5)4], which was used in this work to activate various allenes. Dropwise addition to 2-(trimethylsilyl) penta-2,3-diene yields a bright red solution of a stable Wheland intermediate of ferrocene, whose solid-state structure is depicted as a ball-and-stick model. In front lies Saint Peter’s Key, a prominent feature of the City of Bremen’s coat of arms, representing the unlocked potential of highly reactive main group species. More information can be found in the Research Article by E. Hupf, J. Beckmann and co-workers (DOI: 10.1002/ceur.202500031).
