Abstract
Fully O-alkylated calix[4]arenes have been synthesized by the alkylati on of p-tert-buhlcalix[4]arene and its 1.3-dialkylated derivatives in liquid-liquid phase-transfer catalytic process. 1H(4) and 1H(2)R(2) co uld effeciently be deprotonated by aqueous NaOH (50% w/w)-toluene syst em and alkylated with alkyl (aralkyl. allyl) halogens in good yields a ffording calix[4]arene tetraethers of cone conformation.
