Abstract
Macrorings bearing hexacoordinated phosphorus atoms or (and) tetracoordinated boron atoms, have been prepared from condensation of phenyldichlorophosphane in presence of diethylamine, or (and) boric or phenylboronic acids with some polyphenols. Their structures-have been established by NMR, microanalysis and mass spectrometry. These compounds are constituted according to (1 + 1), (2 + 2) and (3 + 3) stoichiometry.
