The para ‐acylation of calix[4]arene ( 2 ), calix[6]arene ( 3 ), and calix[8]arene ( 4 ) by Friedel‐Crafts reaction with a wide variety of acyl chlorides leads to 5–7 in moderate to good yields. Friedel‐Crafts reaction of 26,28‐dimethoxycalix[4]arene ( 8 ) gave products 9 selectively disubstituted in the para ‐positions of phenol rings.
