Die Reduktion des durch 3:1‐molare Reaktion von Te‐tetrachlorid mit Acetanhydrid in siedendem Chloroform gebildeten Bis‐[telluro]‐methans (I) führt zur polymeren Titelverbindung (II).

The electronic structures study have been used in the classification of tocopherol-rings regiosiomers as antioxidants by quantum chemistry calculations using DFT methods at the B3LYP/6-31G * level of theory. The HOMO, ionization potential, stabilization energies, and spin density distribution calculations were performed for radical formed by electron or hydrogen abstraction from the phenolic hydroxyl groups at the para-, meta-or ortho-positions. These values are related with HOMO and MEPs for antioxidant regioisomers classification. Our results shown that para-regioisomer is more nucleophilic compounds by electron transfer and more reactive molecule by hydrogen donating, followed by ortho-, and meta-regioisomers.

Das nach Schema dargestellte Tetrakis[benzylmercaptolbenzol (V) (Raumgruppe Pl ; Z=1; Fp l47‐ 150°C ; sonst keine Ausb.‐ oder Synthese‐Angaben) ändert in festem Zustand unter Einwirkung von UV‐ oder sichtbarem Licht seine Farbe reversibel ‐von weiß zu dunkelrosa; durch Erwärmen auf 80°C wird die Probe wieder weiß.
