Alternatively, an oxidation mechanism by hydride abstraction might be considered. During our investigations of a Ru/PNNP complex containing a coordinated β-keto ester enolate, we found that Ag+ is able to formally abstract a hydride from the ligand producing an α-alkenyl-β-keto ester [29b]. The removal of a hydride from the aldehyde by silver(I) would directly lead to an α-carbonyl cation. However, we do not have conclusive evidence for such a mechanism.
