“…This is because elements such as halogen and nitrogen are relatively reactive and have a high electronegativity due to their strong ability to attract electrons. The lattice defects and surface holes caused by high electronegativity increase its conductivity 40–42 . In addition, due to the in situ doping of nitrogen and boron elements during the carbonization process, new energy storage sites have been added 43 .…”

Boron carbide powders were synthesized by combustion synthesis using organics chitosan, dextrin, cellulose, starch, and polyvinyl chloride (PVC) as carbon sources. The microwave absorbing properties of boron carbide powders synthesized by different carbon sources were investigated. The results showed that the powders synthesized using organic compounds containing Cl and N atoms as carbon sources have better absorbing properties. The peak value of reflection loss of boron carbide powder prepared with chitosan as carbon source is −46.41 dB at 2.1 mm thickness, with an effective absorption range of 9.21–12.30 GHz and an effective absorption bandwidth of 3.09 GHz. The small and uniform boron carbide grains and residual carbon with multiple morphologies enhance the interface polarization and electronic polarization in the material, which leads to multiple reflections and losses of the microwave. Additionally, the lattice defects and surface holes caused by Cl, N, and other atoms in chitosan and PVC increase the energy storage sites of the material, which makes the materials obtain excellent microwave absorbing properties. Boron carbides fabricated from an organic carbon source provide a potential for the preparation of high‐temperature resistant absorber.

The first example of a diphosphaborolediide, the benzo‐fused [C6H4P2BPh]2− (12−), is prepared from ortho‐bis(phosphino)benzene (C6H4{PH2}) and dichlorophenylborane, via a sequential lithiation approach. The dilithio‐salt can be obtained as an oligomeric THF solvate or discrete TMEDA adduct, both of which are fully characterized, including by X‐ray diffraction. Alongside NICS calculations, data strongly suggest some aromaticity within 12−, which is further supported by preliminary coordination studies that demonstrate η5‐coordination to a zerovalent molybdenum center, as observed crystallographically for the oligomeric [{Mo(CO)3(η5‐1)}{μ‐η1‐Mo(CO)3(TMEDA)}2] ⋅ [μ‐Li(THF)][μ‐Li(TMEDA)].

The (Fmes)BH 2 •SMe 2 reagent (7) reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.
