The initial steps in the catalyst system tungsten hexachloride/tetramethyltin/C//5-olefins have been studied kinetically. UV-vis spectroscopic examinations have shown that the first alkylation step proceeds as a second-order reaction with the low activation energy of 26. 1 kJ mol** minus **1. The reaction between tungsten hexachloride and C//5-olefins leads quantitatively to tungsten pentachloride which is formed as a stable intermediate compound. This reaction, which is much slower than the alkylation step, is of great importance in the presence of high olefin concentrations, and especially in the case of cyclic olefins.
