Summary: In this study, a highly regioselective hydrosilylation of propargylic amines was described for the first time. The reaction utilizes a PtCl2/XantPhos catalyst system to deliver hydrosilanes across the alkyne, resulting in multifunctional allylic amines in high yields. The reaction is tolerant to a wide variety of functional groups and provides high value intermediates with two distinct functional handles, as shown through the synthesis of diverse ambiphilic aziridines.

These new compounds emit intense blue light, some demonstrating fluorescence quantum yields close to unity. The weak aromatic character of the novel 1,2,7-azadiborepin ring was demonstrated through in-depth theoretical investigations using nucleus-independent chemical shift (NICS) scans and anisotropy of the induced current density (ACID) calculations.

Summary: A series of methylene-bridged bis(triarylboranes) were successfully synthesized using metal-free catalytic Si/B exchange condensation under mild conditions. These compounds exhibit effective internal pi-conjugation, but the conjugation between the two borane units is disrupted by the aliphatic linker. Cyclic voltammetry and UV-vis spectra further revealed the electronic structure properties of the compounds.

Summary: Novel alkynyl-functionalized diarylbis(dimethylamino)diboranes(4) were prepared by salt metathesis, and their appended alkynyl groups underwent hydroboration to yield discrete boryl-appended diborane(4) species when reacted with monohydroboranes. Conversely, reactions with dihydroboranes led to the formation of oligomeric species with B-B bonds, with some exhibiting good air stability and solubility in common organic solvents. These oligomeric species, characterized by NMR, vibrational spectroscopy, and size-exclusion chromatography, can contain up to ten repeat units.

Summary: We found that the outcome of the tin-boron exchange reaction depends on the steric bulk of the aryl substituent of the borane reagent, resulting in the formation of either boroles or large diboracycles. NMR spectroscopic studies showed that the two products can reversibly interconvert in solution, and density functional theory calculations revealed boroles to be intermediates in the formation of the diboracyclic products.

Summary: The reaction of a cyclic alkyl(amino)carbene (CAAC)-stabilized thiazaborolo[5,4-d]thiazaborole (TzbTzb) with strong Bronsted acids results in the protonation of both TzbTzb nitrogen atoms. The coordination of counteranions or solvent molecules to the doubly protonated fused heterocycle via hydrogen-bonding interactions influences the visible and fluorescence colors of these salts. DFT calculations show that the hydrogen bonding affects the charge transfer character, enabling fine-tuning of absorption and emission spectral features.

Summary: The incorporation of BN units into organic scaffolds by isoelectronic/isosteric substitution has proven effective in producing new materials. However, the knowledge about BN-doped inorganic-organic hybrid polymers is limited, especially for linear or cyclolinear macromolecules with longer inorganic chains. In this study, 1,2,5-azadiborolane was introduced as a novel building block for polymers. By coupling it with a p-phenylene diamine-based co-monomer, a hybrid polymer with a B2N3 chain and a considerable molecular weight was obtained. The UV-vis spectra revealed a red-shift in the longest-wavelength absorption band with increasing number of BN units in the chain.

Summary: In this study, the treatment of N-silyl-B-chloro-aminoborane was investigated. It was found that substoichiometric quantities of Me3SiOTf led to B-N coupling, whereas activation with 5 mol% of Ag[Al{OC(CF3)(3)}(4)] resulted in Cl/Me exchange between the boron and the silicon center. Combined experimental and computational studies supported a chain reaction initiated by nucleation-limited chloride abstraction in the latter process.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
