✦ Synopsis

Conductometric and Spectroscopic Investigations of the Interaction of Lewis Acids with Halide Complexes

The interaction of counter ions with Lewis acids has been investigated using mode systems of the type (C~6~H~5~)~3~C^⊕^ MX~n+1~^⊖^ (M = Sb, As, B, Fe; X = Cl, F) by means of conductometrical and UV‐spectroscopic methods. The changes of conductivity were strongly dependent on the nature and concentration of the Lewis acid. The results point to 1:1‐complexes between Lewis acids and counter ions. The behaviour was found to be complicated by dissoziation resp. assoziation processes. Ligand exchange reactions between Lewis acid and counter ion have also been found.
