Synthesis, properties, and some rhodium, iridium, and platinum complexes of a series of bulky m-terphenylphosphine ligands
(Elsevier, 2016)
A series of sterically demanding aryl phosphine ligands (L) bearing terphenyl substituents, PR2Ar′ (R = hydrocarbyl, Ar′ = 2,6-diarylphenyl radical) has been prepared and characterized. The stability of these ligands towards ...

Cationic (η5-C5Me4R)RhIII Complexes with Metalated Aryl Phosphines Featuring η4-Phosphorus plus Pseudo-Allylic Coordination
(American Chemical Society, 2018)
In this contribution we study experimentally and computationally some electrophilic cationic (η5-C5Me4R)RhIII complexes containing a cyclometalated bis(aryl) phosphine, PR′Ar2. The phosphine Ar groups feature methyl ...

Evaluating stereoelectronic properties of bulky dialkylterphenyl phosphine ligands
(Elsevier, 2019)
The stereoelectronic properties of a series of sterically hindered phosphines containing a terphenyl substituent, PR2Ar’ (R = alkyl; Ar’ = C6H3-2,6-Ar2), have been evaluated by various methods. Their σ-donating capacity ...

Base-Promoted, Remote C−H Activation at a Cationic (η5 ‑C5Me5)Ir(III) Center Involving Reversible C−C Bond Formation of Bound C5Me5
(American Chemical Society, 2019)
C-H bond activation at cationic [(η5-C5Me5)Ir(PMe2Ar')] centers is described, where PMe2Ar' are the terphenyl phosphine ligands PMe2ArXyl2 and PMe2ArDipp2. Different pathways are defined for the conversion of the five-coordinate ...

Evidence for Genuine Bimetallic Frustrated Lewis Pair Activation of Dihydrogen with Gold(I)/Platinum(0) Systems
(Wiley-Blackwell, 2020)
A joint experimental/computational effort to elucidate the mechanism of dihydrogen activation by a gold(I)/platinum(0) metal-only frustrated Lewis pair (FLP) is described herein. The drastic effects on H2 activation derived ...
