Methods are described for the selective diametrical functionalization of calixarenes at the upper rim, either by the selective removal of the p-tert-butyl groups and subsequent substitution at the free phenol rings or by selective reactions at the phenol rings of dialkoxycalixarenes without the tert-butyl groups.This includes selective mercuration and the synthesis of 5,17-di-tert-butyl-26,28-dimethoxy-11,23-diphenylcalixarene (13), of which the crystal structure is described.The first synthesis of macrocyclic diquinones derived from calixarenes (calixdiquinones) is described.

, p. 2681 - 2684 (2007/10/02)
Methods are described for the selective diametrical functionalization of calixarenes at the upper rim by transfer of functionality and selective substitutions at the para positions of the phenol rings.The crystal structure of 26,28-dimethoxy-11,13-dini
