    • Larock et al. reported copper-catalyzed addition of indole N-H to diphenylacetylene. (6a) However, in our blank experiment in the absence of the rhodium catalyst, any coupling products including 1-vinylindoles could not be detected.

    • Another possible pathway via aminorhodation of 2a by a indolylrhodium intermediate and subsequent cyclorhodation to form B cannot be excluded.
