A tripodal aminothioether ligand scaffold: Synthesis and coordination to zirconium and hafnium

Add time:08/22/2019    Source:sciencedirect.com

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 N4S2 coordination from the ligand, with one diethylamido ligand also bound. The solid state structures of all compounds are reported.
