    • Both O- and C-bound Pd enolates have been characterised in the literature (for examples, see:, D. A. Culkin, J. F. Hartwig, Organometallics 2004, 23, 3398-3416). In a C-bound enolate, the selectivity might be compromised by free rotation of around the C-CHO bond, and as such, we suggest that the O-bound Pd enolate is formed. Importantly, this mechanism requires, for geometric reasons, that hydride delivery and binding of the enolate to palladium take place at different Pd atoms. This can be readily achieved by PdNPs, but is difficult to achieve in solution with mononuclear Pd species.
