摘要

主族元素的协同效应为新型化学转化铺平了道路。然而，以最丰富的铝元素和硅元素为特征的双金属复合物的潜力在很大程度上仍未得到开发。在本研究中，我们介绍了双（硅烷基）稳定铝烯 2 的合成和表征。铝烯和硅烯之间的合作使得亚硝基烯烃中的 N-O 键易于裂解，从而生成铝亚胺络合物 4 以及四环噁唑硅烷 5 和 6，还能促进 2-甲基喹啉的脱芳烃化，生成硅烷 7。此外，2 还是一种有效的前催化剂，可将亚硝基烯烃还原偶联为氮氧烯烃。这些结果概述了一种协调铝和硅合作以促进化学键活化的方法。

Multielectron Reduction of Nitrosoarene via Aluminylene-Silylene Cooperation

The cooperative effects of main-group elements pave the way for novel chemical transformations. However, the potential of bimetallic complexes featuring the most abundant aluminum and silicon elements remains largely unexplored. In this study, we present the synthesis and characterization of bis(silylene)-stabilized aluminylene 2. The cooperation between aluminylene and silylene allows for the facile cleavage of the N–O bond in nitrosoarenes, producing an aluminum imide complex 4 and tetracyclic oxazasilaalanes 5 and 6, and also promotes the dearomatization of 2-methylquinoline, yielding a silylalane 7. In addition, 2 is an effective precatalyst for the reductive coupling of nitrosoarenes to azoxyarenes. These results outline an approach for orchestrating aluminum and silicon cooperation to facilitate chemical bond activation.
