Abstract
[GRAPHICS] p-Benzylcalix[5]arene and p-benzylcalix[7]arene are formed on ultrahigh int ensity grinding (UHIG) of p-benzylcalix[6 or 8]arenes in the presence of KO H and molecular sieves (4 Angstrom), and the same calix[7]arene is also for med on condensation of p-benzylphenol and formaldehyde (15-20% yield), unde r more forcing conditions, along with p-benzylcalix[10]arene.
