Diamidophosphate (DAP) is the simplest phosphorodiamidate ion, with formula PO2(NH2)2−. It is a phosphorylating ion and was first used for the phosphorylation of sugars in aqueous medium. DAP has attracted interest in the area of primordial chemistry.

Salts

Several salts of the formula MPO2(NH2)2(H2O)x are known.

Reactions

Heating anhydrous sodium diamidophosphate causes polymerization:

Heating hydrated salts induces the loss of ammonia to form oligophosphates and polyphosphates.

Diamidophosphate inhibits urease enzymes by blocking up the active site, binding to two nickel centers. Diamidophosphate mimics the urea hydrolysis intermediate.

Diamidophosphate is tribasic, and the amine groups may also lose hydrogen to form more metallic salts. With silver, further reactions can yield explosive salts: tetrasilver orthodiamidophosphate (AgO)3P(NH2)NHAg, and pentasilver orthodiamidophosphate (AgO)3P(NHAg)2.

Organic esters and amides

Phenyl phosphorodiamidate, an inhibitor of urease, is a controlled release fertilizer.

Numerous organic derivatives are known. One example is phenyl phosphorodiamidate.

Reactions with nucleosides

DAP phosphorylates deoxynucleosides (the building blocks of DNA, and at the same time initiates polymerization to make DNA. DAP facilitates the synthesis of larger RNA sequences (ribozymes) from smaller RNA strands. Other nitrogenous derivatives of phosphorus derivatives have also been proposed in this context in a review article.
