N,N'-bis(2-hydroxy-alpha-methylbenzylidene)ethylenediamine synthesis
- Product Name:N,N'-bis(2-hydroxy-alpha-methylbenzylidene)ethylenediamine
- CAS Number:5464-60-8
- Molecular formula:C18H20N2O2
- Molecular Weight:296.36
Yield:5464-60-8 99%
Reaction Conditions:
in methanol; for 1 h;Heating;
Steps:
The tetradentate ligand, N,N′-bis(2-hydroxyacetophenylidene)ethylenediamine, was prepared according to the literature [9]. To a solution of 2-hydroxyacetophenone (0.1 mol, 13.63 g) in 50 mL of methanol was added a solution of ethylenediamine (0.05 mol, 3.01 g) in 50 mL of methanol, and the mixture was stirred for 1 h on a hot-plate. The resulting yellow crystalline material was collected by suction filtration, washed with a small amount of methanol, and dried in vacuo. Yield: 14.78 g (99%). Calc. for H2hapen (C18H20N2O2): C, 72.95; H, 6.80; N, 9.45. Found: C, 72.93; H, 6.82; N, 9.32%. Mp = 193-196 °C.
