Summary: This paper presents a catalytic method for the preparation of deuterated NHCs, using a coordinatively unsaturated Ru NHC catalyst to achieve selective deuterium labeling. Mechanistic studies revealed the high regio-selectivity of this catalytic system, offering a new approach for the synthesis of deuterated NHCs.

Summary: The treatment of potassium salts of silole dianions with donor stabilised germanium dichlorides resulted in the formation of anticipated silagermafulvenylidenes as transient intermediates, rather than the desired products. The main products of these reactions are sila-bis-lambda(3)-germiranes, directly interconnected digermylenes that are part of a three-membered ring. The structural data, supported by density functional calculations, confirm the digermylene nature of these products with a long inner cyclic Ge-Ge bond that decreases the high ring strain in silagermiranes.

Summary: The 4-RN-1,3-Ar-2-imidazolium salt, R = iPr, tBu, Ar = Mes, Dipp, underwent metalation by Au-I at the C2-, C5-, and 4-RN positions, depending on the reactants and conditions used. A rare direct rearrangement of the Au-I aminide to an abnormal imidazol-5-ylidene Au-I complex was also observed, which may involve TfO- facilitated H+ transfer, according to a DFT study.

Summary: The novel silylene-supported iron hydride 1 was synthesized via C(sp(3))-H bond activation and exhibited excellent catalytic activity for hydrosilylation of aldehydes and ketones. It showed good tolerance and catalytic activity for substrates with different functional groups on the benzene ring, with both ketones and aldehydes being reduced in good to excellent yields under the same catalytic conditions. A possible catalytic mechanism was proposed based on experiments and literature reports.

Summary: Homo- and heterodicarbene palladium complexes with caffeine-derived N-heterocyclic carbene ligands were synthesized and characterized. The alkylated caffeine-based salts also exhibited superior acidity, allowing the isolation of zwitterionic caffeine monocarbene palladium complexes with outstanding catalytic activity in the cyanation reactions of aryl halides.

Summary: This study explores the B-H bond activation of pinacolborane using the steric incompatibility of tris(alkyl) gallium GaR3 and N-heterocyclic carbene 1,3-bis(tert-butyl)imidazol-2-ylidene. A novel ion pair was isolated and structurally authenticated, and the reaction mechanism was elucidated through stoichiometric and catalytic studies. The results demonstrate the potential for efficient hydroboration of aldehydes and ketones under mild reaction conditions.

Summary: A Markovnikov-selective hydroacylation of alkenes has been achieved by the synergistic merger of cobalt, photoredox, and N-heterocyclic carbene catalysis. The closely interconnected catalytic cycles enable Co(III) generation through photochemical oxidation, eliminating the need for chemical oxidants or anodizing processes. This mild and operationally simple protocol efficiently converts a wide range of commercially available alkenes and aroyl fluorides into ketones with high yield and branched selectivity.
