Direct reactions of tellurium tetrahalides with chelating nitrogen ligands. Trapping of TeL2 by a 1,2-bis(arylimino)acenaphthene (aryl-BIAN) ligand and C-H activation of an alpha,alpha'-diiminopyridine (DIMPY) ligand.
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 alpha,alpha'-diiminopyridine ligand dpp-DIMPY causes C-H activation of an imino methyl group.
