We report an example in which two different metals with two different phosphine ligands promote two out of three possible reactions and do so in a time-resolved way, thus leading to an efficient preparation of dihydroquinolines. Importantly, we show that one of the two phosphine ligands is selective in binding to only one of the metals, and the other ligand is nondiscriminating in its binding properties; yet one of the two metal-phosphine complexes is far more reactive and selectivity is observed This study raised the more general question of matching ligands and metals in order to efficiently promote only the desired reaction rather than competing processes. Thus, complex sequences of reactions that contain multiple catalytically active species can ultimately be created in a single reaction vessel.
