    • The reader is referred to Baldwin's rules for ring closure, which predict exo- and endocyclic paths to be favourable for aminoallenes. See, for instance: J. March, Advanced Organic Chemistry, Wiley, New York, 1992, 4th edn, pp. 212-214

    • note
    • This needs further elaboration for aminoallene substrates and/or precatalysts that are sterically more encumbered than reactants { 1 + 2} investigated herein. This crucial aspect, however, is beyond the scope of the present study and will be the subject of forthcoming investigations.

    • 7 centre of 5 is predicted to be kinetically impeded, thus being improbable, when compared to the path that commences from 5′ (Tables 3, S1, ESI).

    • The 1,3-hydrogen shift is presumably a viable process. The kinetics of this process has not been investigated in the present study
