Abstract:

The substituted amine-bis(phenol) compound N,N-bis-(4,5-dimethyl-2-hydroxybenzyl)-N(2-pyridylethyl)amine (H₂L) was prepared through a Mannich reaction utilizing two equivalents of a substituted phenol, two equivalents of formaldehyde and a single equivalent of a secondary amine. The organic compound, which may act as a tripodal ligand in coordination complexes, has been characterized by elemental analysis, IR, and ¹H and ¹³C NMR spectroscopies, mass spectrometry (ES) and X ray diffraction spectroscopy.

Keywords: Mannich reaction, bis(phenolate), tripodal ligand
