p - tert -Butylcalixarene hexamethyl ether was oxidized in one step to the corresponding ketocalixarene via photochemical bromination (100 W spot lamp) with NBS in a chloroform/water mixture. A pentamethyl ketocalixarene derivative was obtained by reaction of the ketocalixarene hexamethyl ether with boron tribromide dimethyl sulfide complex, and characterized by X-ray crystallography. In the presence of base, the compound undergoes an intramolecular nucleophilic aromatic substitution reaction.
