Summary: Halogen-substituted silylenes play a crucial role in synthesizing silicon-based low-valent and multiple-bond species. This study presents a convenient synthesis for bromo- and iodosilylene supported by an iminophosphonamide ligand, expanding the limited reports on heavier halosilylenes.

Summary: We have described a family of organoplatinum(II) complexes containing cationic methylstannylene and chloro- and azidosilylene ligands. These complexes are stabilized by coordination to PtII and are formed through facile group transfer reactions. Computational studies have revealed the importance of weak coordination to a neutral ligand, which provides stability to these complexes.

Summary: A series of cationic cyclometalated iridium(III) complexes with o-carborane cage on the main ligand of 2-phenylbenzothiazole were synthesized and characterized. The different substitution positions of o-carborane on the 2-phenylbenzothiazole ring led to significant differences in the emission properties of the synthesized complexes. The presence of an o-carborane fragment promoted strong fluorescence intensity in certain complexes, serving as a tool to effectively enhance fluorescence properties.

Summary: Phosphorescent platinum aryl acetylide complexes supported by tert-butyl-isocyanide and ADC ligands were introduced. The compounds with different substituents on the aryl acetylide exhibited differences in their optical and electrical properties, while the ADC complexes showed higher photoluminescence quantum yields and lifetimes.

Summary: We synthesized an ion pair of cationic and anionic Ir(III) photosensitizers for photocatalytic CO2 reduction. The cationic component provides stability, while the anionic component ensures effective visible-light absorption. [Ir1(+)] acts as the key photoredox species, mainly generated by the transfer of triplet excitation energy from the anionic moiety. The positive photosensitization effect of ion pairing was demonstrated by photocatalytic CO2 reduction in cooperation with a Re(I) molecular catalyst incorporated into a vesicle membrane.

Summary: OATP1B1 and OATP1B3 are drug transporters involved in the uptake of various substances into human hepatocytes. We used a CCF assay to identify substrates of these transporters and tested 30 compounds, finding that some of them are indeed OATP substrates. This finding contributes to our understanding of drug transport mechanisms.

Summary: In this study, diverse polyfunctional substrates were subjected to olefin metathesis reactions in water emulsions using hydrophobic ruthenium catalysts. Instead of using surfactants, ultrasound and microwave techniques were tested on a small scale while conventional heating and mechanical stirring were effective on a larger scale. The developed conditions allowed for low catalyst loadings and simple isolation and purification of the products. The synthetic protocol was successfully applied in the large-scale synthesis of a pharmaceutically related product, sil-denafil (Viagra) derivative.

Summary: This study synthesized three cationic and heteroleptic cyclometalated Ir(III) complexes with dual functions for bacteria imaging and photodynamic therapy. Substitution of phenylpyridine with phenylquinoline isomers enhances UV and visible-light absorbance as well as photoinduced ROS generation ability. Although Ir(1-pq)(2)bP and Ir(2-pq)(2)bP have similar structures and ROS generation ability, the former eradicates bacteria more effectively through photodynamic inactivation under white light.

Summary: We have demonstrated the dimerization and oligomerization reactions of ethylene using bis(phosphino)boryl supported Ni(II) complexes as catalyst precursors. The addition of alkylaluminum(III) compounds or other Lewis acid additives enhances the activity and selectivity of these Ni(II) complexes, leading to the production of butenes and higher olefins. Our studies suggest that this catalysis involves a cooperative activation of ethylene by the Ni-B unit, resulting in the formation of a key borametallacycle intermediate.

Summary: The parent ethylene rhodium(I) complex reacts with internal alkynes to give binuclear metallacycles, which can act as catalytic intermediates in cyclotrimerization reactions. Further reactions lead to unique triple-decker complexes with metal atoms in the central ring. The structures of all three types of complexes have been established by X-ray diffraction.
