Size reduction of metal nanoparticles increases the exposure of metal surfaces significantly, favoring heterogeneous chemistry at the surface of the nanoparticles. The optical properties of metal nanoparticles, such as light absorption, also exhibit a strong dependence on their size. It is expected that there will be strong coupling of light absorption and surface chemistry when the metal nanoparticles are small enough.

- - Pyridinium and related -alkyl(heteroaryl)onium salts are important in organic chemistry for creating various compounds, but their synthesis methods have not advanced much recently.
- - This study introduces a new method using bis(cationic nitrogen-ligated I(iii) hypervalent iodine reagents (HVIs) to efficiently produce a wide range of these onium salts from alkenoic acids, marking a novel approach by directly utilizing olefins.
- - The reactions yield high results in mild conditions, allowing for diverse aromatic heterocycles to be incorporated, and demonstrate significant potential for creating different nitrogen heterocycles through subsequent derivatizations.
