The title compound, [Ir(CH)(CHN)(CHP)]BF, a new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra-fluorido-borate counter-anion, crystallizes with two cations and two anions in the asymmetric unit of space group . The Ir centers of the cations have distorted square-planar conformations, formed by a bidentate (η + η) cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene and a tri-phenyl-phosphane ligand with the NHC carbon atom and P atom being . In the extended structure, non-classical C-H⋯F hydrogen bonds, one of which is notably short (H⋯F = 2.21 Å), link the cations and anions. The carbon atoms of one of the COD ligands are disordered over adjacent sites in a 0.62:0.38 ratio.

We present a bifunctional catalyst consisting of a copper(I)/N-heterocyclic carbene and an organocatalytic guanidine moiety that enables, for the first time, a copper(I)-catalyzed reduction of amides with H as the terminal reducing agent. The guanidine allows for reactivity tuning of the originally weakly nucleophilic copper(I) hydrides - formed in situ - to be able to react with difficult-to-reduce amides. Additionally, the guanidine moiety is key for the selective recognition of "privileged" amides based on simple and readily available heterocycles in the presence of other amides within one molecule, giving rise to hitherto unknown site-selective catalytic amide hydrogenation.

NHC-Au-xanthate complexes.

Institute of Organic Chemistry, Polish Academy of Sciences, 01-224 Warsaw, Kasprzaka 44/52, Poland.

We report the synthesis, isolation, and comprehensive characterization of N-heterocyclic carbene gold xanthate (NHC-Au-X, X - xanthate) complexes. These easily accessible complexes demonstrate significant versatility as photocatalysts, facilitating [2+2]-cycloadditions, and as π-catalysts in the intramolecular hydroxylation of allenes and hydrohydrazination of alkynes.

Acylation stands as a fundamental process in both biological pathways and synthetic chemical reactions, with acylated saccharides and their derivatives holding diverse applications ranging from bioactive agents to synthetic building blocks. A longstanding objective in organic synthesis has been the site-selective acylation of saccharides without extensive pre-protection of alcohol units. In this study, we demonstrate that by simply altering the chirality of N-heterocyclic carbene (NHC) organic catalysts, the site-selectivity of saccharide acylation reactions can be effectively modulated.

High Efficiency and Narrow Emissions in Deep-Blue Pt(II) Emitters in Organic Light-Emitting Diodes via Anchor-Shaped Substituent Design.

ACS Appl Mater Interfaces

January 2025

School of Chemical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, Suwon-si, Gyeonggi-do 16419, Republic of Korea.

In this study, a tetradentate Pt(II) complex designed to have -heterocyclic carbene ligands modified with an anchor-shaped 2,6-diisopropylphenyl (dip) group is described to enhance molecular rigidity for narrow emission and high efficiency. The tetradentate ligand with the dip group significantly hinders steric interactions and restricts π-conjugation from benzocarbene, leading to shallow lowest unoccupied molecular orbital levels and a consequent reduction in the triplet metal-to-ligand charge transfer character. These structural modifications result in narrow emission spectra and enhanced efficiency for blue organic light-emitting diodes (OLEDs) over wide doping concentration ranges.
