Abstract The facile and efficient preparation of pillar[ n ]arenes ( n = 5 or 6) was achieved by cyclooligomerization of 2,5‐dialkoxybenzyl alcohols or 2,5‐dialkoxybenzyl bromides with an appropriate Lewis acid catalyst at room temperature. The mechanism for this cyclooligomerization is presumed to be a Friedel–Crafts alkylation.
