(Quinolinyl)amido-ligated palladium(II) complexes have been synthesized and applied in the catalytic C–H bond arylation of benzothiazoles. The tridentate ligand precursors R2N-C(O)CH2-(NH)-C9H6N [(R2NNN8-Q)–H; R2N = morpholinyl, Me-N-piperazinyl] and the pincerpalladiumcomplexes [κN,κN,κN-R2N-C(O)CH2-(μ-N)-C9H6N}]PdX [(R2NNN8-Q)PdX R2N = Et2N, morpholinyl, Me-N-piperazinyl; X = OAc or Cl}] were
transition-metal complexes have emerged as an excellent solution. In this regard, new aminoquinoline-based copper(II) pincer complexes 1–3 were designed, synthesized, and characterized by modern spectroscopic techniques. It is worth mentioning that, at the highest concentration (1024 μg/mL) of complexes (1–3), the hemolysis was found to be <15%, implying their less toxicity. Further, the complexes effectively

An efficient catalytic protocol for the three‐component assembly of benzyl bromides, carbon monoxide, and alkyl zinc reagents to give benzyl alkyl ketones is described, and represents the first nickel‐catalyzed carbonylative coupling of two sp3‐carbon fragments. The method, which relies on the application of nickelcomplexed with an NN2‐type pincer ligand and a controlled release of CO gas from a solid
