Lithium Di-‐ and Trimethyl Dimolybdenum(II) Complexes with Mo-‐Mo Quadruple Bonds and Bridging Methyl Groups
(American Chemical Society, 2015)
New dimolybdenum complexes of composition [Mo2{μ-Me}2Li(S)}(μ- X)(μ-N^N)2] (3a−3c), where S = THF or Et2O and N^N represents a bidentate aminopyridinate or amidinate ligand that bridges the quadruply bonded molybdenum ...

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 ...

Activation of Small Molecules by the Metal-Amido Bond of Rhodium(III) and Iridium(III) (η5-C5Me5)M-Aminopyridinate Complexes
(American Chemical Society, 2018)
We report the synthesis and structural characterization of five-coordinate complexes of rhodium and iridium of the type [(η5-C5Me5)M(N^N)]+ (3-M+), where N^N represents the aminopyridinate ligand derived from 2-NH(Ph)-6-(Xyl)C5H3N ...

Ligand Rearrangement and Hemilability in R hodium(I) and Iridium(I) Complexes Bearing Terphenyl Phosphines
(Wiley, 2018)
We describe the synthesis of a series of cationic rhodium(I) and iridium(I) compounds stabilized by sterically demanding phosphines that contain a terphenyl substituent, PMe 2 Ar’ (Ar’ = 2,6-diarylphenyl ...

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 ...

A Cationic Unsaturated Platinum(II) Complex that Promotes the Tautomerization of Acetylene to Vinylidene
(Wiley-VCH, 2017)
Complex [PtMe(PMeAr)] (1), which contains a tethered terphenyl phosphine (Ar =2,6-(2,6-PrCH)CH), reacts with [H(EtO)]BAr (BAr =B[3,5-(CF)CH] ) to give the solvent (S) complex [PtMe(S)(PMeAr)] (2⋅S). Although the solvent ...

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 ...
