Simple approach for the synthesis of a 1,1'-(ethane-1,2 diylbis(azanediyl))bis(pentan-2-ol): 13C/1H NMR spectroscopy and electrical characterizations

Abstract

1,1'-(Ethane-1,2-diylbis(azanediyl))bis(pentan-2-ol) a β-aminoalcohol material denoted as 2a has been successfully synthesized. A white highly pure transparent material has been obtained after purification by chromatography techniques. Infrared spectroscopy has been used to identify the −NH and −OH functional groups. 1H and 13C NMR spectroscopy has confirmed the proposed structure. Complex Impedance Spectroscopy indicates an insulator behavior of the studied materials in the 313-393°C temperature range. Conductivity within this material is in intragrain contribution and its activation energy is about 1.3 eV. The physical properties of the studied material allow to consider β-amino alcohols as versatile intermediates for many organic compounds in the making of natural and synthetic originated biologically active compounds. They are widely used as β-blockers, insecticidal agents, and chiral auxiliaries.
