A highly efficient, in situ formed CuCl2/TMEDA catalytic system (TMEDA = N,N,N′,N′-tetramethylethylene-diamine) for the cross-coupling reaction of aryl acetonitriles with benzyl alcohols is reported. This user-friendly protocol, employing a low catalyst loading and a catalytic amount of base, leads to the synthesis of α-alkylated nitriles in up to 99% yield. Experimental mechanistic investigations reveal that the key step of this transformation is the C(sp3)–H functionalization of the alcohol, taking place via a hydrogen atom abstraction, with the simultaneous formation of copper-hydride species. Detailed density functional theory studies shed light on all reaction steps, confirming the catalytic pathway proposed on the basis of the experimental findings.

A base-catalyzed protocol is reported for the construction of 1,3-thiazolidine-2-thione scaffolds bearing quaternary carbon centers from carbon disulfide and α-tertiary propargylamines. The reaction proceeds using low catalyst loading, under ambient temperatures, and in the absence of solvent. Various α-tertiary propargylamines have been employed, affording a series of previously unreported thiazolidine-2-thione compounds and avoiding purification via column chromatography in certain cases. We also describe a one-pot strategy for the synthesis of the same products through a KA2 coupling–CS2 incorporation approach. The reaction mechanism and substituent-dependent catalytic behavior were studied through a combination of detailed experimental and computational studies.

In response to the need for sustainable energy, this study focuses on advancing the electrocatalytic Hydrogen Evolution Reaction (HER). Considering platinum-based catalysts’ efficacy, but acknowledging their cost and scarcity implications, our work pursues Pt content minimization, simultaneously upholding catalytic efficiency. Our approach introduces a precisely engineered nanoarchitecture, leveraging multiwalled carbon nanotubes (MWCNTs) bearing anchored N-heterocyclic carbenes (NHCs). These carbenes form robust covalent bonds with ultrastable, highly crystalline, platinum nanoparticles (PtNPs), establishing MWCNTs-NHC-PtNPs as a highly efficient electrocatalyst. The synergistic effect of NHCs and triazole moieties facilitates controlled nanoparticle growth and stabilization, yielding 2.0 ± 0.3 nm, uniformly distributed {1 1 1}-faceted PtNPs. The as-obtained MWCNTs-NHC-PtNPs nanomaterial exhibits exceptional HER efficiency in 0.5 M H2SO4 with an overpotential of 77 mV at −10 mA cm–2 and a 50 mV dec–1 Tafel slope, despite containing a merely 0.4% Pt/C atomic ratio content, as determined by XPS. Notably, at 200 mV overpotential, the mass activity reaches 8.6 A/mgPt and the specific activity is 53 mA/cm2Pt, highlighting the efficiency of each Pt site within this nanostructure. Cyclic voltammetry reveals a distinctive, reversible PtO/Pt redox process, demonstrating surface-controlled and diffusion-assisted kinetics with charge storage properties that stabilize the electrocatalyst’s electron-surface and facilitate proton reduction. Equally important, the nanoarchitecture prevents aggregation and mitigates Pt irreversible oxidation, showcasing enhanced stability after extensive cycling and exposure to air. Comparative analyses with a control electrocatalyst lacking NHC-PtNPs ligation emphasize the unique role of NHC-Pt (0) bonding in enhancing electrocatalytic efficiency. Comprehensive surface and electronic property analyses validate the potential of the MWCNTs-NHC-PtNPs platform.
