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

rhodium(III)‐catalyzed N−H insertion reaction is developed from the reaction of phosphoryl amides with α‐aryl diazoesters under aerobic and mild conditions, which produce α‐phosphoryl amino esters in good to excellent yields with high selectivity, a broad substrate scope, and a good functional group tolerance. Also, Rh(III)‐catalyzed N−H insertion reaction of alkenyl phosphonic amides with α‐aryl diazoesters

Provided are novel dihydro-1H-phosphole 1-oxide derivatives and a preparation method thereof. More particularly, the dihydro-1H-phosphole 1-oxide derivatives include 1,3-dihydro-1H-2,1-oxaphosphole 1-oxide derivatives and 2,3-dihydro-1H-2,1-azaphosphole 1-oxide derivatives. Further, in the preparation method of a dihydro-1H-phosphole 1-oxide derivative according to the present invention, various phosphinine oxide derivatives may be prepared with high yield by a simple synthesis process by reacting a phosphinic derivative and a vinyl derivative with each other in the presence of a rhodium (Rh) catalyst, an oxidant, and a base.
