Selective Nitration of Calix[4]arene
Kye Chun Nam, Das Soon Kim
Mono and 1,3-dinitrocalix[4]arene 4 and 7 were prepared by the selective benzoylation followed by nitration. Benzoylation of calix[4]arene with benzoyl chloride in the presence of pyridine produced the tribenzoyl and 1,3-dibenzoyl-calix[4]arene selectively depending on the reaction conditions. Nitration of tribenzoyl and 1,3-dibenzoyl-calix[4]arene was conducted with nitric acid in the presence of acetic acid to produce mono and 1,3-dinitrocalix[4]arene. Removal of benzoyl groups was carried out with NaOH in ethanol to give 4 and 7.
