A palladium mediated C–H aziridination reaction of 3,3,5,5-substituted-piperazin-2-ones has been developed using phenyliodonium diacetate (PIDA) and succinic acid to give synthetically useful bicyclic aziridines, in moderate to good yields. Succinic acid was found to be key for selectively promoting C–N bond formation (aziridination) and suppressing competitive acetoxylation. Analysis of the reaction
