Abstract

(matrix presented). p-Benzylcalix[5]arene and p-benzylcalix[7]arene are formed on ultrahigh intensity grinding (UHIG) of p-benzylcalix[6 or 8]arenes in the presence of KOH and molecular sieves (4 Å), and the same calix[7]arene is also formed on condensation of p-benzylphenol and formaldehyde (15-20% yield), under more forcing conditions, along with p-benzylcalix[10]arene.
