Abstract A straightforward arylation of phosphorylamides with arylhydrazines hydrochloride was herein demonstrated. The protocol proceeded in the presence of a catalytic loading of Cu(OAc)2 as the catalyst, DTBP as the external oxidant and Cs2CO3 as the base, but without any ligands. And a series of N-aryl phosphorylamides were successfully obtained in high efficiency (up to 93% yields) with good substituents

When PhRP(O)N3 (R = Ph or t-Bu) is photolysed in dimethylsulphide substantial amounts (22 – 32%) of PhRP(O)N:SMe2 and PhRP(O)NHCH2SMe are produced and rearrangement is less important than in benzene.
