Neutral diborabenzenes – highly electron-rich systems for classical arene-type reactivity, bond activation, and catalysis
Final Report Abstract
Doubly carbene-stabilized diborabenzenes are a new class of compound developed by our group over the last decade, featuring an aromatic six-electron π system and a six-membered B2C4 ring. Although they are isoelectronic to the well-known molecule benzene, they are far more electron rich and reactive. This project aimed to explore the chemistry and reactivity of these species, and resulted in the discovery of a number of new reactivity patterns. While reactions with chalcogens such as sulfur and selenium were successful, the most impactful advances were made in the coordination chemistry of these diborabenzenes. This led to unprecedented and reactive low-coordinate complexes of metals from Groups 8 and 10, and a diverse range of novel reactions thereof. The project also resulted in the publication of four articles in high-quality journals, including the premier journals Angewandte Chemie International Edition, Journal of the American Chemical Society, and Chemical Communications.
