MACROCYCLES [Agrave] ATOMES DE PHOSPHORE ET DE BORE HYPERVALENTS DÉTERMINATION DE LEUR TAILLE PAR SPECTROMÉTRIEDE MASSE
摘要:
Macrorings bearing hexacoordinated phosphorus atoms or (and) tetracoordinated boron atoms, have been prepared from condensation of phenyldichlorophosphane in presence of diethylamine, or (and) boric of 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.
