Neutral sp2–sp3 Diboranes: Structures, Reactivities, and Applications in Organic Synthesis

Year: 2025

Type: article

Abstract: Neutral sp2–sp3 diboranes are characterized by a polarized BB single bond between two electronically and structurally distinct boryl groups, featuring one sp2‐hybridized (three‐coordinate) boron center and one sp3‐hybridized (four‐coordinate) boron center with a neutral Lewis base ligand. Their unique structures and properties have attracted growing research interest, particularly in exploring their reactivities and applications in CB bond formation reactions. This review summarizes recent advancements in the chemistry of neutral sp2–sp3 diboranes, emphasizing their syntheses, structural features, reactivities, and emerging applications as diboron reagents in organic synthesis.
