Phosphorimidazolide information

A phosphorimidazolide is a chemical compound in which a phosphoryl mono-ester is covalently bound to a nitrogen atom in an imidazole ring. They are a type of phosphoramidate. These phosphorus (V) compounds are encountered as reagents used for making new phosphoanhydride bonds with phosphate mono-esters, and as reactive intermediates in phosphoryl transfer reactions in some enzyme-catalyzed transformations. They are also being studied as critical chemical intermediates for the polymerization of nucleotides in pre-biotic settings.^[1] They are sometimes referred to as phosphorimidazolidates, imidazole-activated phosphoryl groups, and P-imidazolides.
