Abstract null null The reaction of sterically hindered benzylic telluride bearing 2,4,6-tris(bis(trimethylsilyl)methyl)phenyl (Tbt) group with 2.0 eq. of n-BuLi and HSi(OMe)3 afforded a 1,4-silicon rearrangement product. This rearrangement is made possible by the intermediacy of a 5-membered silicate. The product may be exploited as a potential motif for the synthesis of numerous multiply bonded systems containing heavier group 14 elements.

Developing organic luminophores with unique capability of strong narrowband emission is both crucial and challenging for the further advancement of organic light-emitting diodes (OLEDs). Herein, a nanographitic fused-nonacyclic π-system (BSBS-N1), which was strategically embedded with multiple boron, nitrogen, and sulfur atoms, was developed as a new multi-resonance thermally activated delayed fluorescence (MR-TADF) emitter. Narrowband sky-blue emission with a peak at 478 nm, full width at half ...

The reversible addition reactions of olefins with a phosphanylalumane, P-Al single bond species, were investigated. The P-Al bond added to ethylene and relatively small terminal alkenes (propylene and hex-1-ene) at room temperature to give the corresponding alkene-adducts. Heating of the terminal alkene-adducts released the corresponding alkenes and regenerated the P-Al bond, but no release of ethylene was observed even under vacuum conditions. The reactivity of ethylene-adduct as a new saturate...

Carbazole-fused azaborines were synthesized via a Buchwald-Hartwig amination followed by a Pd-catalyzed C-H activation-cyclization reaction. These azaborines exhibited red-shifted absorptions and p...

Immune potentiators, termed adjuvants, trigger early innate immune responses to ensure the generation of robust and long-lasting adaptive immune responses of vaccines. Presented here is a study that takes advantage of a self-assembling small-molecule library for the development of a novel vaccine adjuvant. Cell-based screening of the library and subsequent structural optimization led to the discovery of a simple, chemically tractable deoxycholate derivative (molecule 6, also named cholicamide) w...
