They feature either a singlet or a triplet ground state, depending on the electronic properties of the substituents. Triplet nitrenes are highly reactive and their isolation in the condensed phase under ambient conditions is challenging. Here we report the synthesis and isolation of a triplet arylnitrene supported by a bulky hydrindacene ligand. The arylnitrene is fully characterized by various spectroscopic and structural techniques including electron paramagnetic resonance spectroscopy and single-crystal X-ray diffraction. Its high stability is largely attributed to the steric hindrance and effective electron delocalization provided by the supporting ligand. Electron paramagnetic resonance spectroscopy in conjunction with highly correlated wavefunction-based ab initio calculations provides support for a triplet ground state nitrene with axial zero-field splitting D=0.92cm–1 and vanishing rhombicity E/D=0.002.</p> <p> DOI: 10.1038/s41557-024-01669-9</p> <p> Source: <a href="https://www.nature.com/articles/s41557-024-01669-9">https://www.nature.com/articles/s41557-024-01669-9</a></p> </p> <div class="remarks">期刊信息</div> <div class="dd"><p> <strong>Nature Chemistry：</strong>《自然—化学》，创刊于2009年。隶属于施普林格·自然出版集团，最新IF：24.274<br /> <strong>官方网址：</strong><a href="https://www.nature.com/nchem/">https://www.nature.com/nchem/</a><br /> <strong>投稿链接：</strong><a href="https://mts-nchem.nature.com/cgi-bin/main.plex">https://mts-nchem.nature.com/cgi-bin/main.plex</a></p> </div> </div> </div> <style> #footer{ background:#890f0e; text-align:center; padding:10px; color:#FFF; font-size:12px;} #footer a{color:#FFF; font-size:12px;} </style> <div id="footer"><a href="http://www.sciencenet.cn/aboutus/" target="_blank">关于我们</a> | <a href="http://www.sciencenet.cn/shengming.aspx" target="_blank">网站声明</a> | <a href="http://www.sciencenet.cn/tiaokuang.aspx" target="_blank">服务条款</a> | <a href="http://www.sciencenet.cn/contact.aspx" target="_blank">联系方式</a> | <a href="http://www.sciencenet.cn/RSS.aspx">RSS</a> | <a href="mailto:jubao@stimes.cn">举报</a> | <a href="https://stimes.sciencenet.cn/">中国科学报社</a> <br> <a href="https://beian.miit.gov.cn" target="_blank" > 京ICP备07017567号-12 </a> 互联网新闻信息服务许可证10120230008 京公网安备 11010802032783<br>Copyright @ 2007-<script type="text/javascript">var Date22 = new Date();var year22 = Date22.getFullYear();document.write(year22);</script> 中国科学报社 All Rights Reserved<br> 地址：北京市海淀区中关村南一条乙三号 邮箱：blog@stimes.cn <br> <span style="display:none"> <script type="text/javascript"> var _bdhmProtocol = (("https:" == document.location.protocol) ?
