Summary: A series of unique bench-stable rhodium(I) complexes bearing an aryl-substituted 1,3,5-hexatriene chain were synthesized in this study. These complexes were found to function as initiators for the living polymerization of phenylacetylene, resulting in cis-stereoregular poly(phenylacetylene) with well-controlled molecular weight.

Summary: In this study, a one-pot strategy was developed to prepare non-beta-phosphonium functionalized rhoda- and irida-carbolong complexes from an organic multiyne. This strategy allows for the introduction of various beta-substituents into the complexes using different nucleophiles, providing a convenient route for the further development of carbolong chemistry.

Summary: The study describes the first successful example of a catalytic enantioselective intramolecular Tishchenko reaction, leading to the formation of chiral lactones in good yields with up to 91% ee. These enantioenriched lactones were then used for the first synthesis of (S)-cedarmycins A and B.

Summary: The synthesis and characterization of new zirconium permethylpentalene amidinate complexes are described. The monohalide derivatives demonstrate considerable structural diversity as the nature of the amidinate-supporting ligand is changed. Furthermore, slurry-phase ethylene polymerization studies using the complexes provide a direct comparison to the highly active Pn*Zr(CpR)Cl catalyst family.

Summary: Heteroleptic [RhIIICp*(NHC)] and [IrIIICp*(NHC)] complexes with a N-amino acid functionality derived from imidazolium salts were synthesized and characterized. The structure of [RhCp*{kappa 2(C,O)-NHC}Cl] complex 3f was discussed as a pair of diastereomers. The catalysts showed good yields for the transfer hydrogenation of ketones in basic propan-2-ol, and a chromatographic method for measuring compounds in the reaction was validated. These Rh and Ir complexes provide a new approach in developing catalysts based on classical NHC precursors.

Summary: Analysis of bonding contributions in transition metal complexes [(MCp)-Cp-III*(L)XY] (M = Rh, Ir; Cp* = C5Me5; L = CO, CN-, CNR) revealed a variety of new interactions, including direct lateral donations and hybrid donations, accounting for approximately 20% of the electron donation to the pi*(CO) orbitals.

Summary: Here, an improved self-assembling phosphorus ligand based on hydrogen bonding between pyridone/hydroxypyridine in the ligand backbone is reported. The N-pyrrolyl substituents significantly enhance the pi-backbonding properties of the ligand. Rhodium, iridium, and platinum complexes of the ligand were synthesized and characterized using NMR spectroscopy and x-ray crystal structure analysis. The ligand-based catalyst exhibited high catalytic activity and linear regioselectivity in rhodium-catalyzed hydroformylation of 1-octene, as well as in linear regioselective iridium-catalyzed hydroformylation of 1-octene.

Summary: N-Heterocyclic carbenes (NHCs) react with carbodiimides (CDIs) to form betaine adducts with tunable properties, whose stability depends on substituents on CDI nitrogens and configuration is influenced by NHC substituents. Despite being in the early stages, these adducts have been utilized as ligands for transition metals and nanoparticles, as connection points in zwitterionic polymers, and to stabilize distonic radical cations.

Summary: Novel bis(alkyl) complexes supported by N,N,O-tridentate and N,N,O,O-tetradentate amidinate ligands were synthesized using alkane elimination approach. Unexpectedly, the reaction of one of the complexes led to the formation of a novel bis(amide)amidinate complex. These complexes were evaluated as catalysts for alpha-olefins and isoprene polymerization.

Summary: The solution behavior of complex [Rh(COD)(& mu;-OAc)](2) in dichloromethane has been investigated in the absence and presence of PPN+OAc- using multinuclear NMR spectroscopy. The addition of PPN+OAc- results in the generation of [Rh(COD)(OAc)(2)](-) through equilibration. Rapid exchange between different Rh complexes and acetate ligands is observed at room temperature, but freezing the exchange at lower temperatures allows for the coalescence of certain NMR resonances.

Summary: In this study, a novel method for synthesizing metallabenzenes by replacing the phosphorus atom in an aromatic phosphinine ring with transition metal fragments was reported. Iridabenzene and rhodabenzene were successfully synthesized by triggering the replacement of the phosphorus atom with iridium and rhodium fragments, respectively. The aromaticity of the newly synthesized metallabenzenes was evaluated experimentally and theoretically.
