Abstract

Abstract Using 1, 2-dibromoethane,(E)-1, 4-dibromo-2-butene,(Z)-1, 2, 3, 6- tetrahydrophthalic and phthalic acids we obtained along [1+ 1] scheme uncommon macrocyclic compounds containing ester groups, multiple bonds, and amide moieties in the macroheterocycle. The neutralization of bis-acids with ethylenediamine gave the corresponding macrocyclic diammonium salts that on heating to the melting point were ...
