TLDR
In this article, triaryl phosphates were synthesized from white phosphorus and phenols under aerobic conditions and in the presence of iron catalysts and iodine, and the reaction proceeds by formation of PI3, then O=PI(OPh)2 before the final formation of the phosphate.Abstract:
Triaryl phosphates were synthesized from white phosphorus and phenols under aerobic conditions and in the presence of iron catalysts and iodine Full conversion to phosphates was achieved without the use of chlorine, and the reactions do not produce acid waste Triphenyl phosphate, tritolyl phosphate and tris(2,4-di-tert-butyl)phenyl phosphate were synthesized by this method with high selectivities Various iron(III) diketonates were used to catalyze the conversion Mechanistic studies showed that the reaction proceeds by formation of PI3, then O=PI(OPh)2 before the final formation of the phosphate The nucleophilic substitution of O=PI(OPh)2 with phenol to form O=P(OPh)3 was found to be the rate-limiting stepread more

Coordination chemistry of elemental phosphorus
TL;DR: In this article, a review comprehensively covers the coordination chemistry of elemental phosphorus during the years 2011-2020. The main part is dedicated to the activation of white phosphorus mediated by early and late transition metals and its subsequent reactivity once in the coordination sphere of a metal.

Benign Chlorine-Free Approaches to Organophosphorus Compounds
TL;DR: In the quest for alternative environmentally benign technology, several routes have been envisaged starting either from elemental phosphorus or from one of its direct low-valent derivative as hypophosphite as discussed by the authors.
