Pd-Catalyzed Indole Synthesis via C-H Activation and Bisamination Sequence with Diaziridinone.

This work describes an efficient Pd-catalyzed indole synthesis. A wide variety of indoles can be obtained in good yields from readily available vinyl bromides. The reaction likely proceeds through a sequential aryl C-H activation and bisamination of a resulting pallada(II)cycle with diaziridinone.
