per-Hydroxylated Prism[n]arenes: Supramolecularly Assisted Demethylation of Methoxy-Prism[5]arene

[Image: see text] Methoxy-prism[5]arene PrS[5](Me) is demethylated by a supramolecularly assisted reaction. In the presence of a tetramethylammonium cation, PrS[5](Me) is demethylated by BBr(3) in high yield, while in its absence a 55/40 mixture of PrS[5](OH)/PrS[6](OH) is formed. The dealkylation o...

Descripción
Sumario:[Image: see text] Methoxy-prism[5]arene PrS[5](Me) is demethylated by a supramolecularly assisted reaction. In the presence of a tetramethylammonium cation, PrS[5](Me) is demethylated by BBr(3) in high yield, while in its absence a 55/40 mixture of PrS[5](OH)/PrS[6](OH) is formed. The dealkylation of prismarenes, such as PrS[6](R) (R = Et, nPr) and c-PrS[5](Me), can be easily obtained in high yields in the presence of BBr(3).
