Abstract

Condensation of resorcinol and its derivatives with novel phosphonium-substituted acetals under conditions of acidic catalysis yields either calix[4]resorcinols containing four phosphonium fragments or phosphonium salts including diarylmethane moiety depending on the structure of the phosphorus-containing reagent. The latter, in turn, undergo condensation with propionic aldehyde forming new calix[4]resorcinols with alternating phosphonium and ethyl substituents, which have remarkable surface-active properties.
