Summary: The study synthesized ruthenium complexes with a cavity-containing ligand and characterized their structures. Different types of pincer-type ligands were used during the synthesis, forming different complexes through thermal ligand exchange of CO with phosphorus ligands. The experimental results showed that these complexes exhibited catalytic activity and performed well in the hydrosilylation reaction.

Summary: Oxidative addition is a fundamental reaction in organometallic chemistry and catalysis, but examples of P-O bond activation are rare. In this study, we report the ligand-templated oxidative addition of a phosphinite P-O bond in a diphosphinito aniline compound, resulting in the formation of a (PONO)Ni((HPPr2)-Pr-i) complex after proton rearrangement. Notably, the P-O bond cleavage occurs selectively over an amine N-H bond activation. Furthermore, the ligand cannibalization is reversible, as various XPR2 reagents can readily produce different (P2ONO)NiX complexes and free HPiPr(2).

Summary: In this study, a molecule, 4-(3,5-Di-tert-butyl-2-hydroxyphenylamino)-N-(6-methoxypyridazin-3-yl)benzenesulfonamide (LSOAPH2), with a 2-aminophenol group was synthesized and characterized. The o-iminosemiquinonate monoanion (LSOISQ) was obtained through an electrochemical oxidation reaction and its properties were confirmed by spectroscopy. LSOAPH2 and LSOISQ exhibited anticancer activity in human cancer cell lines, with LSOISQ showing superior efficacy compared to LSOAPH2.

Summary: This study investigates the intermediates and role of ancillary ligands in copper(I)-catalyzed intramolecular N-arylation reactions. Solid-state structures of copper(I) species with the reaction substrate and product are reported. In addition, kinetic profiling reveals negligible catalyst deactivation but significant catalyst inhibition. Based on these results, an improved catalytic protocol with sub-mol% catalyst loading has been developed.

Summary: Transmetallation of group 6 thienylene Fischer carbene complexes to Pt-II precursors yielded new examples of neutral platinum(ii) bisethoxycarbene complexes with either 2-thienyl (T) or 5-thieno[2,3-b]thienylene (TT) carbene substituents. These well-defined Pt-II ethoxycarbene complexes displayed marked selectivity for the beta-E isomer in the benchmark hydrosilylation reaction, and showed high recyclability, activity in solvent-free reactions, and tolerance to alkyne functional groups.

Summary: A unique bisphosphine-(NHC-borane) compound was synthesized and its coordination towards gold was studied. The compound supported a bimetallic structure bisphosphine-[NHC-BH3]-(AuCl)(2). The BH3 fragment in the compound was activated upon chloride abstraction from the gold metal center, leading to the formation of a rare Au(4) cluster.

Summary: A series of novel heterobimetallic Pd-II/M-II complexes were synthesized and exhibited a cooperative effect in catalyzing coupling reactions, leading to improved catalytic activity and selectivity for the formation of various Z-alkenes. The homogeneous nature of the catalytically active species was also demonstrated in the study.

Summary: Re(i) tricarbonyl complexes are of interest due to their attractive properties, with multinuclear assemblies offering greater structural diversity. Despite synthesis challenges, tetranuclear Re(i) tricarbonyl metallacycles with square geometry were successfully prepared using a tetrazole-based ligand, demonstrating the potential for producing similar structures with suitable ligands.

Summary: The synthesis of well-defined heterometallic complexes is a challenging frontier in inorganic chemistry. A new approach involving sequential insertion of electrophilic metal fragments into electron-rich Ru-B bonds has been reported, leading to the selective preparation of bimetallic and trimetallic complexes. Structural and theoretical analysis of chemical bonding features within Ru-B-B-Cu and Ru-B-B-Pd fragments were presented.

Summary: The monomeric complex (DMAT)(2)Ba.(THF)(2) was synthesized with high stability and solubility, showing an increasing trend of charge delocalization down group 2. Chiral isomers exist in equilibrium in solution and temperature-dependent NMR studies revealed decreasing Ae-C and Ae-N bond energies down the group. Double deprotonation reactions produced the first Ba imido complex and comparative studies with other Ae metal complexes showed stable tetramers with ionically bound cores.

Summary: A series of Rh-I complexes with cationic diphosphinometal ligands (PMPn+) were synthesized, and the impact of Rh-I -> Mn+ interactions on other ligands coordinated to the Rh-I center was studied. It was found that the Rh-CO bond strength in square pyramidal [(PMP)Rh(CO)X](n+)-type complexes (X = Cl, H) is primarily influenced by the charge of the metalloligand. Computational analysis of octahedral [(PMP)Rh(CO)(2)H](n+) model complexes indicated a strengthening of the Rh-CO bond trans to the metalloligand with increasing atomic number of the metalloligand.

Summary: The impact of metalloligands on Au catalysed alkyne hydrofunctionalisation is investigated, with ambiphilic PMP-type ligands (M = Cu-I, Ag-I, Zn-II) stabilizing Au -> M bonds, including unprecedented Au-I ? Zn-II interactions. The Lewis acidity of Au increases in the order Cu-I < Ag-I < Zn-II, promoting catalytic cycloisomerisation of propargylamide 14. Au/Zn complex 8 serves as an excellent catalyst for alkyne hydroamination.
