The alkylation steps in the catalyst system tungsten hexachloride/tetramethyltin have been studied kinetically. FTIR examinations in combination with UV and GC results have shown that the alkylation of tungsten hexachloride is accompanied by a reduction of the tungsten component. Ether addition increases the amount of the tungsten chloride which is reduced.
