It is a common heterocyclic compound, the chiral-nitrogen-ligands compound, Tris[2-(dimethylamino)ethyl]amine, cas is 33527-91-2 its synthesis route is as follows.
Ni(CH3COO)2 (53 mg, 0,30 mmol) was dissolved in the smallest possible amount of methanol while an excess of Me6TREN was dissolved in acetone. After addition of the second solution to the first one, a change in colour from light blue to green was observed. An excess of KPF6, dissolved in acetone, was added to the previous solution in order to promote the anion metathesis reaction. The solvent was evaporated and the green solid obtained was dissolved in pure acetone. A white solid remained undissolved on the bottomof the flask (CH3COOK) and was filtered off. The solution was dried under vacuum and the solid dissolved in dichloromethane in order to eliminate the excess of KPF6. After filtration of the solid residue,the solution was reduced in volume and the pure product 2 was precipitated upon addition of n-pentane. Crystals suitable for XRD were grown at low temperature by slow diffusion of n-pentane into a dichloromethane solution of 2. Yield: 86%; Anal. Calc. for[Ni(L1)(CH3COO)](PF6)H2O: C, 32.90; H, 6.90; N, 10.96. Found: C,33.23; H, 6.97; N, 10.93%.
