Mechanistic and reactivity insights into diboron-mediated N=N and N-N bond scission
Diboron reagents have emerged as versatile reducing agents capable of transforming a broad range of functional groups through pathways like hydrogen- or metal–hydride-based reductions. Moreover, the strong thermodynamic driving force for B─O bondf ormation enables efficient cleavage of X─O bonds and...

| Sumario: | Diboron reagents have emerged as versatile reducing agents capable of transforming a broad range of functional groups through pathways like hydrogen- or metal–hydride-based reductions. Moreover, the strong thermodynamic driving force for B─O bondf ormation enables efficient cleavage of X─O bonds and straight forward deoxygenation without the need for external hydrogen sources such as water or alcohol. This intrinsic reactivity can be further enhanced by bases or Lewis-basic additives, including pyridines, which promote B─B bond activation and broaden the scope of transformations accessible under mild conditions. The effectiveness of diboron-mediated X─O bond cleavage naturally raises the question of whether these reagents might also promotethe scission of N─N bonds─a transformation of increasing interest due to the prevalence of N─N motifs in synthetic intermedi-ates, pharmaceuticals, and nitrogen-rich frameworks. This review outlines current understanding of diboron-mediated N═N andN─N bond cleavage and unifies mechanistic and reactivity insights to guide future advances in diboron-based synthetic transformations |
