Cyclophosphorylation of polyphenols by diamidoarylphosphites

It was found that the cyclophosphorylation of polyphenols by diamidoarylphosphites proceeds via the rupture of only one P–N bond and one P–O bond, the second P–N bond remaining intact. It is supposed that the unusual lack of reactivity of the P–N bond is due to the spatial arrangement of the amido g...

Description
Summary:It was found that the cyclophosphorylation of polyphenols by diamidoarylphosphites proceeds via the rupture of only one P–N bond and one P–O bond, the second P–N bond remaining intact. It is supposed that the unusual lack of reactivity of the P–N bond is due to the spatial arrangement of the amido group with respect to the reaction site in phosphorylated intermediates 5 . Graphic
