Structural and Electronic Properties of Boranes Containing Boron-Chalcogen Multiple Bonds and Stabilized by Amido Imidazoline-2-imine Ligands

Juan Pablo Martinez et al.

Summary: The investigation of stabilizing elusive monomeric species containing multiple boron-chalcogen bonds has led to the preparation of a series of neutral chalcogenboranes using a specific ligand. The bonding properties of these compounds were evaluated using a pi-backdonation model, revealing enhanced bonding properties for certain ligand variations. The analysis is expected to contribute to the optimization of existing ligands and the development of new boron chemistry.

Unraveling the reactivity of a cationic iminoborane: avenues to unusual boron cations

Rui Guo et al.

Summary: In this study, a cationic iminoborane compound was synthesized and characterized. It was found that the compound exhibited both B-centered Lewis acidity and BN multiple bond reactivities, allowing for the construction of various tri-coordinate boron cations. Additionally, initial reactions involving coordination, addition, and cycloadditions were observed, demonstrating the potential to build numerous organoboron species via several synthetic routes.

Reactions of a Four-Membered Borete with Carbon, Silicon, and Gallium Donor Ligands: Fused and Spiro-Type Boracycles

Zeynep Gueven et al.

Summary: Donor-acceptor cyclopropanes or cyclobutanes serve as versatile reagents in the synthesis of complex organic (hetero)cycles. This study extends this concept to boron containing heterocycles, demonstrating ring expansion and fusion reactions. The formation and absorption properties of these new compounds are further elucidated through (TD-)DFT calculations.

Reductive Al-B σ-Bond Formation in Alumaboranes: Facile Scission of Polar Multiple Bonds

Zeynep Guven et al.

Summary: This study presents an easy way to access alumaborane species with electron precise Al-B sigma-bond. The reductive rearrangement of certain compounds leads to the formation of alumaborane species with a covalent Al-B sigma-bond. The Al-B sigma-bond can perform reductive scission of multiple bonds, resulting in the incorporation of different bridging groups.

Hadi Dolati et al.

Summary: A new amido imidazoline-2-imine ligand system (HAmIm) has been developed for the isolation of stable boron and chalcogen boranes, showing improved chemical stability and enhanced sigma- and pi-donation compared to traditional systems. The discovery suggests potential applications in certain fields where the HAmIm ligand class may outperform the widely employed NacNac system.

A Cyclic Iminoborane-NHC Adduct: Synthesis, Reactivity, and Bonding Analysis

Abhishek Koner et al.

Summary: A new synthetic strategy was developed to prepare a highly stable cyclic amino iminoborane carbene complex, showing unprecedented thermal stability. Furthermore, the formation of the chemical bond can be explained as a donor-acceptor interaction, resulting in a different electronic structure of the B=N pi-bond.

Give me five - an amino imidazoline-2-imine ligand stabilises the first neutral five-membered cyclic triel(i) carbenoides

Lars Denker et al.

Summary: The study introduces cyclic five-membered triel(i) carbenoides E(AmIm) for E = Ga, In, Tl, bridging the gap between four- and six-membered triel(i) carbenoides supported by HGiso and HNacNac. Ga(AmIm) is found to act as a strong sigma-donor ligand in transition metal complexes, and the intermediacy of Al(i) carbenoide Al(AmIm) is rationalized based on the isolation of an Al(iii) insertion product.
