Synthesis of new ionophilic SNS ligands and their Ru(II) complexes

Abstract:

Ruthenium complexes have many applications among them that their use in advanced material synthesis and heterogeneous catalysis. Developing the ligand is of great importance and this is of influence on the yield and selectivity of reaction, and especially to allow reuse of the catalyst. Taskspecific ionic liquids (TSILs) are commonly used as ligands for metallic complexes, due to their easily tunable properties and, specifically, ionophilic ligands can provide the advantages of strong interaction with ionic liquids as solvents, which reduces the loss of catalyst and its subsequent reuse. Tridentate pincer ligands containing the SNS moiety (SCH2CH2NHCH2CH2S) were selected mainly for application in ester hydrogenation/ dehydrogenation reactions.
