Direct reactions of tellurium tetrahalides with chelating nitrogenligands. Trapping of TeI2 by a 1,2-bis(arylimino)acenaphthene (aryl-BIAN) ligand and C–H activation of an α,α′-diiminopyridine (DIMPY) ligand

Abstract

The reaction of TeI₄ with the 2,6-diisopropylphenyl-substituted 1,2-bis(arylimino)acenaphthene ligand dpp-BIAN results in two-electron reduction of tellurium and formation of the complex (dpp-BIAN)TeI₂, while treatment of TeCl₄ with the α,α′-diiminopyridine ligand dpp-DIMPY causes C–H activation of an imino methyl group.
