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 and structural characterization of a binuclear iridium complex with bridging, bidentate N-heterocyclic carbene coordination of 2, 2 ':6 ', 2''-terpyridine
(Royal Society of Chemistry, 2009)
Thermal activation of terpyridine in the presence of an unsaturated Ir(III) fragment stabilized by a hydrotris(pyrazolyl) borate ligand gives rise to mononuclear complex 2 and binuclear 3, in which the polypyridine ...

Different coordination modes of an aryl-substituted hydrotris(pyrazolyl) borate ligand in rhodium and iridium complexes
(Elsevier, 2011)
Complexes TptolRh(C2H4)2 (1a) and TptolRh(CH2C(Me)C(Me)CH2) (1b) have been prepared by reaction of KTptol with the appropriate [RhCl(olefin)2]2 dimer (Tptol means hydrotris(3-p-tolylpyrazol-1-yl)borate). The two complexes ...

Synthesis and structure of mixed carboxylate-aminopyridinate and -amidinate complexes of dimolybdenum and ditungsten
(Elsevier, 2015)
We describe in this paper the synthesis and structural characterization of dimolybdenum and ditungsten complexes with MM bonds derived from the metal–metal bonded tetracarboxylates [M2(O2CR)4] and incorporating one or two ...

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 ...

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 ...

Synthesis and Reactivity toward H2 of (h5- C5Me5)Rh(III) Complexes with Bulky Aminopyridinate Ligands
(American Chemical Society, 2015)
Electrophilic, cationic Rh(III) complexes of composition [(η5-C5Me5)Rh(Ap)]+, (1+), were prepared by reaction of [(η5-C5Me5)RhCl2]2 and LiAp (Ap = aminopyridinate ligand) followed by chloride abstraction with NaBArF (BArF ...

N-substituted Aminobiphenyl Palladacycles Stabilized by Dialkylterphenyl Phosphanes: Preparation and Applications in C[sbnd]N Cross-coupling Reactions
(Elsevier, 2021)
Neutral and cationic N-methyl- and N-phenyl-2-aminobiphenyl methanesulfonate palladacycles stabilized with dialkylterphenyl phosphanes have been prepared and characterized. Neutral structures are favored with the less bulky ...

Synthesis and reactivity of half-sandwich (η 5 -C 5 Me 5 )Ir(iii) complexes of a cyclometallated aryl phosphine ligand
(Royal Society of Chemistry, 2011)
Reaction of the Ir(iii) dimer [(η 5 -C 5 Me 5 )IrCl 2 ] 2 with PMeXyl 2 (Xyl = 2,6-C 6 H 3 Me 2 ), in the presence of the poorly coordinating base 2,2,6,6-tetramethyl piperidine, gives a chloride complex 1-Cl, resulting ...

Quadruply bonded dimolybdenum complexes with highly unusual geometries and vacant coordination sites
(Royal Society of Chemistry (Great Britain), 2012)
New quadruply bonded dimolybdenum complexes of the terphenyl ligand Ar Xyl2 (Ar Xyl2 = C 6H 3-2,6-(C 6H 3-2,6-Me 2) 2) have been prepared and structurally characterized. The steric hindrance exerted by the Ar Xyl2 groups ...
