| | 1-(2-Aminoethyl)pyrrolidine Usage And Synthesis |
| Chemical Properties | CLEAR COLORLESS TO LIGHT BROWN LIQUID | | Uses | 1-(2-Aminoethyl)pyrrolidine may be used in the preparation of one-dimensional coordination polymer of nickel(II), [(μN,S-NCS)2{Ni(ampy)}]n (ampy=1-(2-aminoethyl)pyrrolidine). | | General Description | 1-(2-Aminoethyl)pyrrolidine is a heterocyclic building block. Nickel(II) salts of 1-(2-aminoethyl)pyrrolidine have been synthesized and thermal studies have been reported. The isomeric complexes trans-[NiL2(NCS)2] (violet) and cis-[NiL2(NCS)2] (blue) [L=1-(2-aminoethyl)pyrrolidine] have been synthesized and their X-ray crystal structure have been studied. | | Synthesis | Add (1-pyrrole) acetonitrile, Raney nickel and methanol (400 mL) in a 1L hydrogenation kettle. Inert the hydrogenation kettle, control the internal temperature of 20-30 , continuous through the hydrogen to maintain the pressure of 0.4-0.5 MPa, hydrogenation reaction until the hydrogen is not consumed. Hydrogenation is completed, filtration, and methanol (50 ml * 2) wash, collect the filtrate and wash. The residue was concentrated to dryness by distillation under reduced pressure. Then distillation under reduced pressure, collect (boiling point: 100-105 / 60mmHg) fraction, obtained colorless liquid 1-(2-aminoethyl)pyrrolidine 35.9 g, yield 85.5%, purity 99.0% (GC). |
