General description

4-Imidazolecarboxaldehyde undergoes reductive amination with the amine in the presence of sodium borohydride to form secondary amines.

Application

4-Imidazolecarboxaldehyde may be used in the following studies:
  • Synthesis of new donor-Π-acceptor (D-Π-A) type dye.
  • Preparation of ethyl, n-dodecyl and n-hexadecyl esters of urocanic acid (4-imidazoleacrylic acid).
  • Fabrication of colorimetric chemosensor.
  • Synthesis of chiral nickel(II) complex, [Ni(II)H3L](ClO4)2, having an achiral ligand H3L (tris{2-(4-imidazolyl)methyliminoethyl}amine).

A new donor-π-acceptor (D-π-A) type dye was synthesized by the condensation reaction between 2-cyanomethylene-3-cyano-4,5,5-trimethyl-2,5-dihydrofuran and 4-imidazolecarboxaldehyde. The chemical structure of the dye was characterized by (1)H NMR, EA and MS. A novel chromogenic dye based on imidazole as donor unit
