features streamlined Ti-mediated alkyne reduction, leading to Z-olefins, followed by direct lithiation and borepin formation. These molecules allow for an assessment of aromatic competition between the fused rings and the central borepin core. Crystallographic, magnetic, and computational studies yielded insights about the aromaticity of novel, differentially fused [b,f]borepins and allowed for comparison
该报告描述了一系列带有两种不同芳烃融合基的基于三联环基的基于多环芳烃的多环芳烃的合成和表征。硼烷的合成具有流线型的Ti介导的炔烃还原作用,导致Z-烯烃,然后直接锂化和硼烷形成。这些分子可以评估稠合环和中心孔销之间的芳香竞争。晶体学,磁性和计算研究产生了关于新型,差异融合的[ b,f ] borepins芳香性的见解,并可以与文献化合物进行比较。还将多个Borpin基序掺入到在主骨架中具有5个或6个环的多环芳烃中,并评估了它们的性能。
