Kinetics of the ligand exchange reactions between bidentate ligands and rriethylenetetramine nickelate (II) and synthesis of boron (III) subphthalocyanines with various boron substitutions
<p>Part 1. The kinetics of the ligand exchange reaction between 5-methyl-1,10-phenanthroline and triethylenetetramine nickel (II) were studied spectrophotometrically over the pH range of 5.2 to 8.0 at 25oC. A ternary complex Ni(Trien)(5MP) forms within a few seconds and subsequently reacts with 5MP …
