An Unsymmetrical, Cyclic Diborene Based on a Chelating CAAC Ligand and its Small-Molecule Activation and Rearrangement Chemistry

Wei Lu et al.

Summary: A one-pot synthesis of a CAAC-stabilized, unsymmetrical, cyclic diborene was achieved through consecutive two-electron reduction steps, resulting in a diborene with a smaller HOMO-LUMO gap. Complexation with [AuCl(PCy3)] led to two diborene-Au-I pi complexes, while reactions with different reagents led to cleavage of various bonds, and thermal rearrangement gave rise to an electron-rich cyclic alkylideneborane that easily coordinated to Ag-I.

Main Group Multiple Bonds for Bond Activations and Catalysis

Catherine Weetman

Summary: This Minireview discusses the rapid expansion of molecular main group multiple bonds after the discovery of breaking the double-bond rule. While these compounds show potential in small molecule activation and mimicking transition metals, their catalytic behavior is somewhat limited. The review aims to highlight the potential of these complexes in catalytic applications and further functionalizations, serving as versatile tools for modern synthetic chemists.

A N-Phosphinoamidinato NHC-Diborene Catalyst for Hydroboration

Jun Fan et al.

Summary: The N-phosphinoamidinato NHC-diborene catalyst 2 can efficiently activate ammonia-borane and carbon dioxide, as well as exhibit catalytic capability with chemoselectivity towards carbonyl compounds. The B=B double bond in compound 2 plays a key role in activating substrates for hydroboration reactions with pinacolborane, leading to high conversion rates and yields in the formation of various boron-containing products.

Andreas Stoy et al.

Summary: Reduction of B2X4(NHC)(2) yields green 1,2-dihalodiborenes B2X2(NHC)(2) with short B=B double bonds and reversible one-electron oxidation to diboron radical cations. UV-vis, computational analysis, and X-ray diffraction confirm the correlations between properties such as HOMO localization, HOMO-LUMO energies, and chemical reactivity.
