Special Issue Information

Dear Colleagues,

The Special Issue "Boron Chemistry and Applications" serves as a comprehensive platform to introduce the intricate world of boron chemistry, shedding light on recent advancements and multifaceted applications. Boron, with its unique chemical properties and versatile reactivity, has captivated the interest of researchers across various disciplines, paving the way for groundbreaking discoveries and innovative solutions.

One of the key focal points of this Special Issue is the exploration of boronyl synthons, which serve as versatile building blocks in organic synthesis, enabling the construction of complex molecular architectures with precision and control. The strategic incorporation of boron-containing groups in organic molecules not only enhances their reactivity but also opens up new avenues for the synthesis of pharmaceuticals, agrochemicals, and advanced materials.

In addition, this Special Issue explores the intriguing realm of boron-based materials, which have garnered significant attention for their exceptional properties and wide-ranging applications. Furthermore, it delves into the realm of boron-based catalysts, which play a crucial role in facilitating a myriad of chemical reactions with precision and efficiency. The unique electronic structure of boron compounds enables them to act as potent catalysts in diverse transformations, driving innovation and sustainability in the field of catalysis. In the realm of medicinal chemistry, boron emerges as a promising player, particularly in the realm of boron neutron capture therapy (BNCT), a cutting-edge cancer treatment modality that harnesses the unique properties of boron-10 to selectively target and destroy cancer cells. The development of boron-containing compounds for BNCT has immense potential for revolutionizing cancer treatment, offering a targeted and minimally invasive approach that holds promise for improving patient outcomes.
Beyond these specific areas of focus, this Special Issue also aims to capture the broader landscape of boron chemistry, encompassing both fundamental research and practical applications across various disciplines.

In conclusion, the Special Issue "Boron Chemistry and Applications" stands as a testament to the vibrant and ever-evolving field of boron chemistry, showcasing the ingenuity and creativity of researchers as they push the boundaries of knowledge and explore the vast potential of boron-based innovations. This Special Issue serves as a catalyst for inspiration and discovery, paving the way for a future where boron chemistry continues to thrive and make a profound impact on society.

Amino acids with unusual types of chirality and their derivatives have recently attracted attention as precursors in the synthesis of chiral catalysts and peptide analogues with unique properties. In this study, we have synthesized a new nido-carborane-based planar-chiral amino acid, in the molecule of which the amino group is directly bonded to the B(3) atom, and the carboxyl group is attached to the B(9) atom through the CH2S+(Me) fragment. 3-Amino-9-dimethylsulfonio-nido-carborane, prepared in three steps from 3-amino-closo-carborane in a high yield, was a key intermediate in the synthesis of the target planar-chiral amino acid. The carboxymethyl group at the sulfur atom was introduced by the demethylation reaction of the dimethylsulfonio derivative, followed by S-alkylation. The structure of new 3,9-disubstituted nido-carboranes was studied for the first time using NMR spectroscopy. The resonances of all boron atoms in the 11B NMR spectrum of 3-amino-9-dimethylsulfonio-nido-carborane were assigned based on the 2D NMR correlation experiments. The nido-carborane-based planar-chiral amino acid and related compounds are of interest as a basis for peptide-like compounds and chiral ligands. Full article

An efficient cross-coupling of aryl bromides with sodium sulfinates, using an organoboron photocatalyst with nickel, is described herein. Under the irradiation of white light, this dually catalytic system enables the synthesis of a series of sulfone compounds in moderate to good yields. A broad range of functional groups and heteroaromatic compounds is tolerated under these reaction conditions. The use of an organoboron photocatalyst highlights a sustainable alternative to iridium or ruthenium complexes. These findings contribute to the field of photochemistry and provide a greener approach to sulfone synthesis. Full article

The present study is a theoretical investigation into the structural evolution, electronic properties, and photoelectron spectra of phosphorus-doped boron clusters PBn0/− (n = 3–17). The results of this study revealed that the lowest energy structures of PBn− (n = 3–17) clusters, except for PB17−, exhibit planar or quasi-planar structures. The lowest energy structures of PBn (n = 3–17), with the exceptions of PB7, PB9, and PB15, are planar or quasi-planar. The ground state of PB7 has an umbrella-shaped structure, with C6V symmetry. Interestingly, the neutral cluster PB15 has a half-sandwich-like structure, in which the P atom is attached to three B atoms at one end of the sandwich, exhibiting excellent relative and chemical stability due to its higher second-order energy difference and larger HOMO–LUMO energy gap of 4.31 eV. Subsequently, adaptive natural density partitioning (AdNDP) and electron localization function (ELF) analyses demonstrate the bonding characteristics of PB7 and PB15, providing support for the validity of their stability. The calculated photoelectron spectra show distinct characteristic peaks of PBn− (n = 3–17) clusters, thus providing theoretical evidence for the future identification of doped boron clusters. In summary, our work has significant implications for understanding the structural evolution of doped boron clusters PBn0/− (n = 3–17), motivating further experiments regarding doped boron clusters.
