CsF-promoted acetyl dance at the narrow rim of p-tert-butyl[3.1.3.1]homooxacalixarene.
In the acetylation of an oxygenated calix[4]arene homologue in the presence of CsF as a base, relaxation of the reaction system to the equilibrium composition takes place through several intra- and intermolecular steps that can be easily controlled to obtain the various acetyl derivatives. The effect of different bases is also discussed.
