RETRACTED ARTICLE: Schiff base transition metal complexes for Suzuki–Miyaura cross-coupling reaction
Schiff base ligand and its complex with iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu) ions were synthesized using 4-aminoacetophenone and salicylaldehyde and characterized. FTIR spectrum shows that bidentate coordination of metal ions with ligand where O, N are electron donating sites of azome...

| description | Schiff base ligand and its complex with iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu) ions were synthesized using 4-aminoacetophenone and salicylaldehyde and characterized. FTIR spectrum shows that bidentate coordination of metal ions with ligand where O, N are electron donating sites of azomethine group. The geometry of the complexes was deduced from the calculated magnetic moment values and SCXRD analysis. All complexes were studied for their catalytic activity in Suzuki–Miyaura cross-coupling reaction with

complex showing excellent coupling yield among others. The catalytic activity data show promising results in coupling efficiency, employing cheap, abundant and green metals.
Graphical Abstract
Synopsis
The transition metal Schiff base complexes synthesized and characterized by SCXRD, Mass spectrometry, TGA, UV–Vis and FTIR analysis. Magnetic susceptibility measurements were also examined to know the plausible geometry of the complex. The synthesized complexes were systematically investigated for Suzuki–Miyaura cross-coupling reactions and optimized to enhance the yield of the Suzuki reaction. |
