    • Coupling of the allene sp carbon with carbonyl groups is much more common in intramolecular reactions, where geometric constraints of ring closure play a substantial role. See Vol. 2 of Ref. 7 for examples.

    • note
    • In the case of 2,3-nonadiene ('methyl vs n-hexyl'), 1:1 site selectivity was observed, but the allylic:homoallylic selectivity was 93:7, and the Z/E ratio of the allylic product was >95:5, as observed in all other cases. See Section 7 for details.
