Six N^C^N cyclometalated Ni(II) complexes [Ni(N^C^N)Cl] or [Ni(N^C^N’)Br] with symmetric non-symmetric N^C^N’ ligands in which the peripheral N-groups were varied pyridine (Py), 4-thiazole (4Tz), 2-thiazole (2Tz), and 2-benzothiazole (2Btz) complementing previously reported di(2-pyridyl)phenide [Ni(Py(Ph)Py)X] X = Cl Br. The synthesized from NiBr2 N^CH^N’ protoligands through base-assisted nickelation, while received N^C(Cl)^N [Ni(COD)2] (COD 1,5-cyclooctadiene). Introduction of 4Tz on both...
We present a novel copper-catalyzed method for aniline cross-couplings promoted by 6-hydroxy picolinhydrazide ligand. The achieves room-temperature reactivity with aryl bromides, enabled methanol/ethanol solvent mixture and mild, functional group-compatible base, catalyst loadings as low 0.5 mol %. use of industrially preferred solvents well the high catalytic activity, offers significant advancement in practicality scalability industrial processes. Furthermore, approach extends to...
Biaryl amines are essential structural motifs prevalent in agrochemicals, pharmaceuticals, and materials. Herein, we present a novel copper-catalyzed method for aniline cross-couplings promoted by 6-hydroxy picolinhydrazide ligand. The achieves room-temperature reactivity with aryl bromides, enabled methanol/ethanol solvent mixture mild, functional group-compatible base, catalyst loadings as low 0.5 mol%. use of industrially preferred bases solvents, well the high catalytic activity, offers...
