Summary: Due to their versatile reactivities, acylsilanes have been extensively used in organic synthesis. However, in the last two years, unprecedented wide applications of this compound have been observed in various fields beyond organic synthesis, such as photo-click reactions for polymer-backbone editing, catalytic Fisher carbene formation, and acylsilane-hydroxylation ligation. The recent development of a quick synthetic method for acylsilanes further enhances the attractiveness of this chemistry. This highlight article showcases selected representative examples and highlights their potential utilities in the future.

Summary: In this study, four planar cyclometalated platinum(II) complexes with enlarged aromatic rings were evaluated as effective anticancer theranostic agents for the first time. The increased number of aromatic rings in the N?N ligand led to increased lipophilicity and cytotoxicity selectivity. The interaction between the complexes and biomolecules was indicated by enhanced NIR and green emissions, with different distributions and induction of cell death efficiency.

Summary: A mono-substituted Au(I) carbene was synthesized by reacting HC(N-2)(Dmp) (Dmp = 2,6-dimesitylphenyl) with an (o-carboranyl)-diphosphine AuNTf2 complex. It exhibited stability up to about 10 degrees C and its structure was determined using NMR spectroscopy. Density functional theory calculations revealed that the chelating P<^>P ligand enhanced Au -> C-carb backdonation, while the Dmp substituent provided kinetic stabilization without altering the electronic structure of the carbene complex.

Summary: In this study, a series of novel NHC-Au(I) complexes derived from 4,5-diarylimidazole and glycyr-rhetinic acid (GA) were designed and synthesized. Among them, complex 4C exhibited excellent tumor targeting and antitumor activity, inducing immunogenic cell death (ICD) in hepatocellular carcinoma (HCC) cells. Furthermore, 4C effectively inhibited TrxR enzyme activity, increased reactive oxygen species (ROS) expression, disrupted redox homeostasis, caused mitochondrial dysfunction and endoplasmic reticulum stress (ERS), and led to the release of damage-associated molecular patterns (DAMPs) in HCC cells. Importantly, 4C showed a strong ICD-inducing effect in a vaccination mouse model and activated antitumor immunity in a tumor-bearing C57BL/6 mouse model, consistent with the in vitro results. In conclusion, Au(I) complexes with HCC-targeted capability have the potential for effective tumor immunotherapy.

Summary: The self-assembly of mechanoluminochromic polynuclear gold(I) complexes has attracted increasing attention in the field of supramolecular gold(I) chemistry. In this study, two polynuclear gold(I) supramolecular clusters with Au4 and Au16 cores were successfully constructed through cooperative interactions. One of the clusters exhibited intense emission in both the solid state and in solution, while the other cluster showed reversible mechanochromic luminescence behavior in the solid state.

Summary: The role of indium carboxylate precursors in synthesizing monodisperse InP quantum dots was explored. The presence of carboxylic acid affected the reaction kinetics and optical properties of the InP QDs, leading to less controlled formation of nanocrystals. Luminescent quantum dots with a gradated ZnSeS shell were successfully obtained from the synthesized InP core.

Summary: The catalytic formation of borylamines from atmospheric N2 was achieved for the first time using a series of homogeneous (triphosphine)Mo complexes. Stepwise functionalization of the (triphosphine)Mo-nitrido complex with chloroborane led to the synthesis of the imido complex. Electrochemical characterization revealed that the (PPP)Mo-borylimido complexes are more easily reduced than the (PPP)Mo-nitrido complexes.

Summary: The reduction of a high spin paramagnetic complex by two electrons under N-2 resulted in the formation of two isomeric low spin diamagnetic complexes, which were successfully isolated and characterized. DFT calculations provided insights into the mechanism of double alpha,alpha CH bond insertion into a single sp(3) CH2 moiety. Fast exchange positions of hydrides in the cis dihydride complex were observed using NMR spectrocscopy.
