catalyst for the n‐butyl complex relative to complexes with smaller Me and Et substituents. As is common in hydrogenation reactions, the activity of the complexes decreases in the order Ru>Ir>Rh. The application of [Ru(p‐cym)Cl(L)]PF6, which outperforms its reported analogues, has been successfully extended to the hydrogenation of more challenging biomass‐inspired substrates.
Three iron complexes having bidentate 1-(2-aminophenyl)-substituted imidazol-2-ylidene ligands were synthesized by reactions of Cp*FeN(SiMe3)2 (Cp* = η5-C5Me5) with the corresponding imidazolium iodides. These iron complexes exhibited high catalytic performance for dehydrogenation of ammonia-borane in the presence of KN(SiMe3)2. The structure of an active species was determined by its NMR and high
