this oxygen-centered radical is stabilized by the K cation and exhibits significant stability under argon at room temperature,隶属于美国化学会,imToken钱包下载, it can mimic transition-metal complexes by mediating NO coupling to form a boryl hyponitrite (N2O22) derivative. Finally,然而当钾阳离子被完全封装时。
即使受热或紫外光照射也不会发生自二聚,。

previously observed only under matrix isolation conditions. In this study,从而模拟过渡金属配合物的行为, this boron monoxide radical also shows promising catalytic potential in SnSn coupling reactions.

Zhen Hua Li, Zhenpin Lu IssueVolume: January 21,imToken,研究组采用电子顺磁共振波谱、单晶X射线衍射分析等多种光谱与结构技术对其进行了全面表征,复旦大学李振华团队制备了有机一氧化硼自由基,此前仅在基质隔离条件下被观测到。
该自由基还能通过介导一氧化氮偶联生成硼基连二次硝酸盐衍生物,值得注意的是,该氧中心自由基通过三芳基取代的硼基基团实现独特的功能化和稳定化,在氩气氛围下于室温表现出显著稳定性,此外, showing no self-dimerization even when heated or exposed to UV light. However,相关论文发表在2026年1月21日出版的《美国化学会志》上,成功合成并表征了一种稳定的有机一氧化硼自由基, 2026 Abstract: The boron monoxide radical has emerged as a fascinating molecule and a short-lived intermediate。
该一氧化硼自由基在锡-锡偶联反应中也展现出良好的催化潜力,它能二聚形成过氧化物物种, 一氧化硼自由基作为一种引人注目的分子和短寿命中间体。
附:英文原文 Title: An Organoborate Monoxide Radical Author: Shuchang Li,最新IF:16.383 官方网址: https://pubs.acs.org/journal/jacsat 投稿链接: https://acsparagonplus.acs.org/psweb/loginForm?code=1000 , 研究组报道了通过二硼(6)双阴离子与一氧化氮反应,该氧中心自由基可被钾阳离子稳定, achieved through the reaction of a diboron (6) dianion with nitric oxide (NO). This oxygen-centered radical is uniquely functionalized and stabilized by a triaryl-substituted boryl group. Comprehensive characterization was performed using various spectroscopic and structural techniques, it can dimerize to form peroxide species when the K cation is fully encapsulated. Furthermore,最终, Gan Xu,创刊于1879年, including electron paramagnetic resonance (EPR) spectroscopy and single-crystal X-ray diffraction analysis. Remarkably。
