Solid‐state structures reveal that in bromide 2, directing NH–anion interactions position the bromide ion in an η1‐type fashion over but not in the center of the aromatic ring. The same directing forces are effective in corresponding tribromide salt 3. In the crystal, the bromide ion is paneled by four electron‐deficient aromatic ring systems. In addition, compounds 4 and 6, which have triiodide and the

Primary and secondaryamines condense with benzotriazole and a polyfluoroaldehyde to give products which are reduced by sodium borohydride to give the corresponding secondary and tertiary amines containing polyfluoroalkyl groups.
