Regiochemistry of Reactions of 2-Chloro-4(5)-dichlorophosphinyloxybenzo-1,3,2-dioxophospholes with Phosphorus Pentachloride and Chlorine

摘要

Polyphenols are widely used in various fields of chemistry as scaffolds of supramolecular systems [1], for preparation of polydentate ligands, as additives in polymer composites [2], etc. Inclusion of phosphorus fragments into such compounds provides for their fire resistance [3-5]. Simple polyphenols, such as pyrogallol I and oxyhydroquinone II, are convenient models to study phosphorylation of more complex natural systems. Nevertheless, we have not come across any systematic study of phosphorylation reactions of polyphenols with most common phosphorylating agents such as phosphorus halides.
