The chemistry of heterocycles containing "diaza" units has been extensively studied due to their applications ranging from pharmaceuticals to advanced materials. In contrast, heterocycles incorporating heavier elements, such as Sb and Bi, remain exceedingly rare and lack straightforward synthetic methodologies. Herein, we present a comprehensive experimental and theoretical investigation of the first diazadistiboylidenes (, ), synthesized via a [3 + 2]-cycloaddition between a distibene and diazoolefins.

Taxa-4,11-diene is made by the taxa-4,11-diene synthase (TxS) from Taxus brevifolia. The unique reactivity of the taxane system is characterised by long distance hydrogen migrations in the biosynthesis. This study demonstrates that selective long range hydrogen migrations also play a role in the high energy process of the EI-MS fragmentation of taxa-4,11-diene.

EWSR1/FUS::TFCP2-rearranged rhabdomyosarcoma (RMS) is a rare tumor with an aggressive clinical course, a predilection for craniofacial bones, spindled and/or epithelioid histomorphology, and positive immunohistochemistry (IHC) for epithelial and myogenic markers, along with variable ALK expression. Herein, we present four additional cases of primary cutaneous TFCP2-rearranged RMS. Notably, one tumor (case 1) displayed a varied pathological spectrum, initially presenting as a low-grade spindle cell neoplasm, but progressed into a high-grade spindle/epithelioid tumor.

Surface oxidation/reduction processes, driven by varying electrochemical potentials, can substantially impact catalyst effectiveness and, consequently, electrolyzer performance. This study combines theoretical and experimental approaches to explore the surface redox behavior of nickel oxides, which are cost-effective and efficient catalysts for many electrochemical reactions. Surface Pourbaix diagrams for three different phases of nickel oxides, i.
