Abstract

The presented mini-review summarizes the results of our study of the condensation of resorcinol and its derivatives with phosphorylated acetals, aldehydes, and vinylphosphonates with an aim to prepare new calix[4]resorcinols (thio)phosphorylated on the lower rim of macromolecule. The properties of the synthesized macrocyclic compounds are studied and some aspects of their possible application are considered. [ABSTRACT FROM AUTHOR]

Abstract

ABSTRACT The reactions of linear polyphenols containing phosphonium fragment with formaldehyde and morpholine (Mannich reaction), as well as with propionic aldehyde, have been studied. As a result, calix[4]resorcinols of novel type have been synthesized, which contain alternating methylphosphonium and ethyl substituents. The structure and composition of the products obtained were confirmed according to 1H and 31P nuclear magnetic resonance, mass spectrometry, and elemental analysis data. [ABSTRACT FROM AUTHOR]
