Synthesis of new chiral and nonchiral N2O2 and N2S2 tetradentate ligands and their metal complexes

摘要

N,Nu0002-Bis(3-aryl-3-oxoprop-1-enyl)diamines and N,Nu0002-bis(3-aryl-3-thioxoprop-1-enyl)diamines are synthesisednby condensation of chiral or nonchiral diamines on the corresponding functionalised ketoenolate 2 or dithiolyliumnsalt 4. Complexation of the obtained N2O2 and N2S2 ligands with transition metals is investigated.
