Here, we present a detailed study of the phosphate aryne reaction. We demonstrate that phosphates, phosphate esters and anhydrides are arynophiles, which can be converted into Oarylated phosphate derivatives. Starting from various substituted Kobayashi aryne precursors, we reacted the derived arynes with inorganic phosphate (Pi, 17) and pyrophosphate (PPi, 18) towards arylated mono- (21) and diphosphates (22). In addition, phosphomonoesters (19) are selectively transformed into arylphosphodiesters (23). Notably, the method is applicable to cyclic condensed phosphates (20, also known as metaphosphates), leading to storable arylated cyclophosphate species (24) of controllable ring-size, which have rarely been described. These species in turn are versatile oligophosphorylation reagents, linearizable by e.g. amine nucleophiles. We evaluate this concept up to an unprecedented one-flask octaphosphorylation reaction, but this appears not to be the limit. Overall, the scope of the aryne phosphate reaction is demonstrated in 48 examples covering a broad range of phosphates and aryne precursors.
