Modification of α,β-conjugated enol-keto containing compound towards to the synthesis of ethyleneimine compound and its complexes with Co(II)

This project was aimed to synthesize the allylideneamine moiety ligand in order to replace the phenylpyridine (ppy) moiety ligand in the metallacycle complexes. The L series compounds were synthesized by reacting p-(R)-acetophenone (R = H or NO2) to glyoxal through cross-adol condensation reactio...
