Rauch, Michael published the artcileMetal-Ligand Cooperation Facilitates Bond Activation and Catalytic Hydrogenation with Zinc Pincer Complexes, COA of Formula: C23H43NP2, the publication is Journal of the American Chemical Society (2020), 142(34), 14513-14521, database is CAplus and MEDLINE.
A series of PNP zinc pincer complexes capable of bond activation via aromatization/dearomatization metal-ligand cooperation (MLC) were prepared and characterized. Reversible heterolytic N-H and H-H bond activation by MLC is shown, in which hemilability of the phosphorus linkers plays a key role. Utilizing this zinc pincer system, base-free catalytic hydrogenation of imines and ketones is demonstrated. A detailed mechanistic study supported by computation implicates the key role of MLC in facilitating effective catalysis. This approach offers a new strategy for (de)hydrogenation and other catalytic transformations mediated by zinc and other main group metals. Safety: caution advised with pyrophoric organozinc compounds, gas evolution at high temperature and reactions involving H2.
