Rhodium and Iridium β-Diiminate Complexes – Olefin Hydrogenation Step by Step

“…Moreover, the methylene carbon is seen to be coupled to both hydrogens (J ϭ 108 and 141 Hz), but shows no measurable coupling to Rh. Close approach of an NBE methylene hydrogen to a metal has also been observed in [17] but in the three other NBE complexes for which X-ray structures have been reported the distances between the metal and the methylene bridges are much larger: [18] Pt(NBE) 3 (PtC ϭ 3.20/3.13/3.16 Å , PtH ϭ 2.65/ 2.80/3.01 Å ), [19] and a dicopper complex (CuC ϭ 2.96/2.97 Å , CuH ϭ 2.50/2.51 Å ). [20] The observation of a pronounced agostic interaction in L Me Rh(NBE) provides little information concerning the strength of this interaction.…”

Pt0 and Pd0 Olefin Complexes of the Metalloid N‐Heterocyclic Carbene Analogues [EI(ddp)] (ddp=2‐{(2,6‐diisopropylphenyl)amino}‐4‐{(2,6‐diisopropylphenyl)imino}‐2‐pentene; E=Al, Ga): Ligand Substitution, HH and SiH Bond Activation, and Cluster Formation

“…The final H 2 O content in all solvents was checked by Karl-Fischer titration and did not exceed 5 ppm. [PtA C H T U N G T R E N N U N G (cod) 2 ], [34] [Pd 2 A C H T U N G T R E N N U N G (dvds) 3 ], [27] [GaA C H T U N G T R E N N U N G (ddp)], [6] and [Al-A C H T U N G T R E N N U N G (ddp)] [5] were prepared according to literature methods. Elemental analyses were performed by the Microanalytical Laboratory of the Ruhr-Universität Bochum.…”

Synthesis and Crystal Structures of Zerovalent Platinum η2-Fumarate Bis(norbornene) Complexes and Their Application as Hydrosilylation Catalysts

“…The synthesis of such complexes usually starts from [Pt(cyclooctadiene) 2 ] 1,2 or one of the numerous other platinum(0)-alkene complexes such as 3 ], 2 [Pt(η 2 -norbornene) 3 ], 3,4 [Pt(η 2 -styrene) 3 ], 5 [Pt(dibenzylideneacetone) 2 ], 6 [Pt 2 (η 4 -divinyltetramethyldisiloxane) 2 (µ-η 4 -divinyltetramethyldisiloxane)], 7 and [Pt 2 (η 4 -hepta-1,6-diene) 2 (µ-η 4 -hepta-1,6-diene)]. 8 Over the years, many other platinum(0)-alkene complexes have been reported, including a large amount of "mixed" alkene complexes, such as [Pt(η 4 -cyclooctadiene)(η 2 -dimethyl fumarate)], 9,10 [Pt(η 2 -tetrafluoroethene)(η 2 -norbornene) 2 ], 11 [Pt(η 2 -2-methylnaphthoquinone)(η 2 -norbornene) 2 ], 12 and [Pt 2 (µ-η 4 -p-benzoquinone) 2 (η 2 -norbornene) 2 ].…”
