A convenient, inexpensive synthesis of the previously reported, well-defined complex Ni(tmeda)(o-tol)Cl is described. This protocol enables rapid and safe access to Ni(tmeda)(o-tol)Cl, obviating the use of the hazardous reagent AlMe₃ or air-sensitive Ni(COD)₂. Ni(tmeda)(o-tol)Cl is prepared at room temperature from commercially available and easily synthesized precursor Ni(acac)₂ and can be isolated at gram scale in air via simple filtration. We expect this simple method to be attractive to chemical industry and academia given the types of solvents, reaction temperature, and reagents used.

Ni（tmeda）（o-tol）Cl 的实用、大规模制备


描述了先前报道的、定义明确的复合物 Ni（tmeda）（o-tol）Cl 的一种方便、廉价的合成。该方案能够快速安全地获得 Ni（tmeda）（o-tol）Cl，避免使用有害试剂 AlMe₃ 或空气敏感的 Ni（COD）₂。Ni（tmeda）（o-tol）Cl 是在室温下从市售且易于合成的前驱体 Ni（acac）₂ 制备的，可以通过简单的过滤在空气中以克级分离。考虑到溶剂的类型、反应温度和使用的试剂，我们预计这种简单的方法对化学工业和学术界具有吸引力。
