A tripodal aminothioether ligand scaffold: Synthesis and coordination to zirconium and hafnium. (10th January 2017) - Mdluli, Velabo
Graphical abstract: The synthesis of a new tren-based N4 S3 ligand and its metalation chemistry with zirconium and hafnium including the solid state structures of the ligands and metal complexes. Abstract: The heptadentate ligand, tris-(2-(2-(methylthio)phenylamino)ethyl)amine (2 ), has been synthesized from the condensation of nitrilotriacetyl chloride with 2-(methylthio)aniline, to generate 2, 2′, 2″-nitrilotris( N -(2-(methylthio)phenyl)acetamide) (1 ), followed by a lithium aluminum hydride reduction. The zirconium (3 ) and hafnium (4 ) complexes of this ligand were generated via transamination reactions. Both complexes are isostructural, exhibiting a hexadentate N4 S2 coordination from the ligand, with one diethylamido ligand also bound. The solid state structures of all compounds are reported.
