In some cases low (⩽18%) yields of dialkyl alkyl-3H-azepin-7-ylphosphonates are formed, indicating the intermediacy of nitrenoid species. Reaction of triethylphosphite with p-ethyl-, p-methyl-, and p-methoxynitrobenzenes, and of trimethyl phosphite with o-nitroanisole and p-nitrotoluene give low yields of the corresponding dialkyl arylphosphonates, representing the first recorded instances of displacement

This communication describes the first phosphoramidate directing group for synthetically useful arylation. Remarkably, the nature of a new directing group drives selective C–H bond activation to afford diverse N-aryl phosphoramidates in good to excellent yields at roomtemperature.
