N-[2-(4-Methoxyphenyltelluro)ethyl]phthalimide: Synthesis and complexation with palladium(II)

Pt, Pd and Hg Complexes with Potentially Tridentate Telluroether Ligands

“…Depending on the metal ion, telluroethers 1 – 6 can act as monoanionic tridentate chelators, as found in the majority of the structurally characterized Pd 2+ and Pt 2+ complexes. When deprotonation is not possible (as for ligand 1 ), N , Te ‐coordination is observed for Pd 2+ under conservation of a cis ‐PdCl 2 unit 15. A specific feature of Schiff bases 3 is the influence of the size of the alkyl chain on the coordination modes of the ligands in a way that the ligands with ethylene bridges act as tridentate O,N,Te‐donors, whereas monodentate tellurium coordination is observed for the propylene derivatives 17.…”

Tellurated heterocycles, 2-[(2-thienyltelluro)methyl]tetrahydrofuran (L1) and [(2-thienyltelluro)methyl]tetrahydro-2H-pyran (L2): Synthesis and complexation reactions with Pd(II), Pt(II), Hg(II), Ru(II) and Cu(I)

“…Tellurium containing derivatives of heterocycles have been designed and used as ligands but in most of the asymmetric telluride ligands [RR 0 Te], having heterocyclic group [7][8][9][10][11][12][13][14][15][16] the other group is phenyl (or its substituted derivative). Some symmetric telluride ligands [R 2 Te] are also known in which two heterocyclic groups (R) are identical [13][14][15][16].…”

Emerging trends in organotellurolate chemistry derived from platinoids

“…72 The trans conguration was also obtained by ligand systems like 4 oxatellurane, 73 1,3 dihydrobenzotellurophene, and 2,7-dihydro-1H-dibenzotellurophene ligands. 74 A comparative study of bidentate ligand RECH 2 ER (R ¼ Me, Ph and E ¼ S, Se, Te) 75 with both metals showed that the thio analogs led to a very stable compound, 89 with a possible one or more donor atoms, like oxygen and nitrogen, other than just the available tellurium atom (Scheme 5). Obviously, both metals (Pd, Pt) are directly bonded to tellurium with weak interactions through the donor atoms.…”
