Diastereoselectivity in chiral ruthenium complexes of bidentate bisphosphine monoxide ligands : controlling epimerization in aldehyde complexes and 16 -electron intermediates
TL;DR: Heterobidentate and hemilabile ligands involving P,O-donor chelates produce chiral metal centers when bound to arene−ruthenium complexes as mentioned in this paper.

Heterolytic dihydrogen activation in an iridium complex with a pendant basic group
TL;DR: Experimental and theoretical studies show that H2 reacts with an Ir phosphine complex having a basic pendant amino group to give either an H2 or an Ir-H···H-N hydrogen-bonded hydride complex, depending on the basicity of the phosphine ligands as mentioned in this paper.

Site Preference Energetics, Fluxionality, and Intramolecular M−H···H−N Hydrogen Bonding in a Dodecahedral Transition Metal Polyhydride†
Abstract: Two successive decoalescence events in the hydride region of the 1H NMR spectrum of [ReH5(PPh3)2(py)] (py = pyridine) are now firmly associated with turnstile and pseudorotation fluxionality mechanisms by eliminating an alternative pairwise mechanism. Ab intio (B3LYP) calculations on ReH5(PH3)2L (L = pyridine) have located the transition state for the turnstile mechanism, which proves to be a second dodecahedral tautomer of the starting complex with the pyridine in the normally unfavorable A site. The fluxional process can therefore be considered as an interconversion of two dodecahedral tautomers, and the barrier for the process is identical with the energy difference of the two tautomers. From a comparison in ReH5(PPh3)2L (L = 2-(acetylamino)pyridine and 4-(acetylamino)pyridine), it is clear that having a potentially hydrogen-bonding NH group at the ortho or para positions of the pyridine ring causes an acceleration of the fluxionality, as a result of intramolecular Re−H···H−N hydrogen bonding. The theo...
