Phosphorylation of C - H bonds of aromatic compounds using metals and metal complexes

Key achievements and current trends in the development of methods for phosphorylation of aromatic C - H bonds catalyzed by metal salts and complexes are considered. The most important and promising approaches of the last decade, including those concerning the synthesis and properties of arylphosphonates, are distinguished. Methods for the introduction of a phosphonate group into non-activated and functionally substituted aromatic compounds and heteroaromatic molecules and phosphorylation cyclization reactions involving acetylenes, 2-isocyanobiphenyls and alkynoates are analyzed. The possibilities of ligand-directed phosphorylation of compounds with aromatic C - H bonds and presumed mechanisms and intermediates in the C - P bond formation reactions are considered. The potential of this extensively developing research trend in organic and organoelement chemistry is highlighted.
