Conversion of CO2 to Organic Products in the Presence of Metal Chlorides with Substituted Perimidine Ligants

In this study, substituted perimidine ligant systems (L1and L2) derived from 2-pyridinecarboxaldehyde/quinoline-2-carboxaldehyde and 1,8-diaminonaphthalene has been synthesized. The structures of these compounds were characterized by means of NMR (1H and 13C) spectra, FT-IR spectra, UV-Vis spectra, mass spectra, melting point measurements, as well as elemental analysis (C, H, N). The obtained and fully chatacterized compounds (L1and L2) and metal salts (ZnCI2 ve CuCI2) were used together as insutu catalytic system and investigated their activity. The in situ system of L2 ligant bearing the quinoline-2-carboxaldehyde and ZnCI2 showed superior activity (90.4% yield and 99.4% selectivity)
