Metallocomplex catalyst of the addition reaction of CCl4 to ethylene

The catalyst Fe^IIFe₂ ^IIICl₈ (DMA)₆-iron(2+)diiron(3+)octachlorohexakis(dimethylacetamide), was isolated from the media of the catalytic synthesis of 1,1,1,3-tetrachloropropane (C₃), and characterized by physicochemical methods. A counter synthesis of the catalyst was carried out. The telomerization of ethylene with CCl₄ proceeds with a 98% selectivity with respect to C₃ in its presence, while the conversion of CCl₄, reaches 55–60% after 4 h. A coordination-ionic mechanism of the reaction of CCl₄ with C₂H₄ was proposed, which followed the concept of the donor-accpetor electron-transporting systems (the DAET systems), thus accounting for its high selectivity.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2794–2798.
