A Practical, Large Scale Preparation of Ni(tmeda)(o-tol)Cl

A convenient, inexpensive synthesis of the previously reported and 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 the air-sensitive Ni(COD)2. Ni(tmeda)(o-tol) is prepared, from the commercially available and easily synthesized precursor, Ni(acac)2 at room temperature and the product 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.
