The reaction of uranyl nitrate hexahydrate with p-benzylcalix[7]arene (H7L) in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) resulted in the formation of the compound (UO22+)6(L7-)2

(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 ?), 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.

The condensation of p-benzylphenol and formaldehyde in tetraline in the presence of potassium hydroxide affords, in addition to the "easy" calixarenes (n=6 and 8), the cyclopentamer (n=5) in 33percent yield.
