dc.description.abstractIn this study, four novel metallophthalocyanine (MPc) compounds derived from phthalonitrile ligands incorporating o-vanillin were synthesized, characterized, and evaluated as pre-catalysts in the acetophenone and benzaldehyde transfer hydrogenation (TH) reactions. The molecular structures of the complexes were confirmed by FTIR and UV-Visible spectroscopy and elemental analysis. Among the complexes, copper phthalocyanine compound (5) exhibited the highest catalytic efficiency, promoting the acetophenone and benzaldehyde transfer hydrogenation reactions in propan-2-ol under inert conditions, and the corresponding alcohols have a 98 % conversion rate within 1 h (A1) and 99 % conversion within 6 h (K1). The results show that both the electronic effects of substituents on the phthalonitrile ligands and the central metal nature play key roles in determining the catalytic performance of the MPc complexes in TH reactions.
