Hydrido{(acylphosphine)(diphenylphosphinous acid)}rhodium(III) Complexes. Catalysts for the Homogeneous Hydrolysis of Ammonia- or Amine-Boranes under Air

10-10-2014 | Virginia San Nacianceno; Lourdes Ibarlucea; Claudio Mendicute-Fierro; Antonio Rodríguez-Diéguez; José M. Seco; Itzia ..., Organometallics, 2014

The reaction of [RhCl(COD)]2 (COD = 1,5-cyclooctadiene) with PPh2(o-C6H4CHO) (Rh/P = 1:1) in the presence of 4-methylpyridine (4-pic) or isoquinoline (iquin) leads to hydridoacyl complexes [RhHCl(PPh2(o-C6H4CO))L2] (L = 4-pic, 1; iquin, 2). Their reaction with diphenylphosphine oxide affords ...

08-10-2014 | Nadine Laskowski; Konstantin Junold; Claudia Kupper; Johannes A. Baus; Christian Burschka; Reinhold Tacke, Organometallics, 2014

Reaction of the donor-stabilized silylene 1 (which is three-coordinate in the solid state and four-coordinate in solution) with organic 1,3-dienes (2,3-dimethyl-1,3-butadiene, 1,3-butadiene, (E,E)-1,4-diphenyl-1,3-butadiene, 2,3-dibenzyl-1,3-butadiene, 1,3-cyclohexadiene, or cyclooctatetraene) ...


Mechanochemical Synthesis of [1,3-(SiMe3)2C3H3]3(Al,Sc), a Base-Free Tris(allyl)aluminum Complex and Its Scandium Analogue

08-10-2014 | Nicholas R. Rightmire; Timothy P. Hanusa; Arnold L. Rheingold, Organometallics, 2014

Unsolvated tris(allyl)aluminum, (C3H5)3Al, has never been isolated, although adducts with THF, OPPh3, and pyridine are known. Attempts to make a base-free derivative with the bulky 1,3-bis(trimethylsilyl)allyl anion (A′) from the reaction of aluminum halides and K[A′] in ethers or by ...


Effects of PAr3 Ligands on Direct Arylation of Heteroarenes with Isolated [Pd(2,6-Me2C6H3)(μ-O2CMe)(PAr3)]4 Complexes

08-10-2014 | Masayuki Wakioka; Yuki Nakamura; Yoshihiro Hihara; Fumiyuki Ozawa; Shigeyoshi Sakaki, Organometallics, 2014

The palladium-catalyzed direct arylation of heteroarenes with aryl halides has attracted considerable attention as a simple cross-coupling process that does not need organometallic reagents. It is generally accepted that this catalysis proceeds via an arylpalladium carboxylate intermediate, which ...


Stereoelectronic and Catalytic Properties of Chiral Cyclometalated Phospha-palladium and -platinum Complexes

07-10-2014 | Yu-Xiang Jia; Bin-Bin Li; Yongxin Li; Sumod A. Pullarkat; Kai Xu; Hajime Hirao; Pak-Hing Leung, Organometallics, 2014

The stereoelectronic properties of palladium(II) and platinum(II) complexes containing ortho-metalated (1-(diphenylphosphino)ethyl)naphthalene were examined by X-ray crystallography in the solid state and by NMR spectroscopy in solution. The studies revealed that the aromatic carbon induced a ...


Synthetic, Structural, and Spectroscopic Studies of Sterically Crowded Tin–Chalcogen Acenaphthenes

02-10-2014 | Kasun S. Athukorala Arachchige; Louise M. Diamond; Fergus R. Knight; Marie-Luise Lechner; Alexandra M. Z. Slawin; J. ..., Organometallics, 2014

A series of sterically encumbered peri-substituted acenaphthenes have been prepared containing chalcogen and tin moieties at the close 5,6-positions (Acenap[SnPh3][ER], Acenap = acenaphthene-5,6-diyl, ER = SPh (1), SePh (2), TePh (3), SEt (4); Acenap[SnPh2Cl][EPh], E = S (5), Se (6); ...


Synthesis and Characterization of Crotyl Intermediates in Rh-Catalyzed Hydroformylation of 1,3-Butadiene

02-10-2014 | Sebastian Schmidt; Eszter Baráth; Tanja Prommnitz; Tobias Rosendahl; Frank Rominger; Peter Hofmann, Organometallics, 2014

Crotyl rhodium complexes like (κ2-L)Rh(η3-crotyl) and (κ2-L)Rh(η3-crotyl)(CO) (L = chelating phosphorus ligand) are important intermediates in hydroformylation catalysis of butadiene and related reactions. They are assumed to be responsible for the specific reactivity patterns of conjugated ...


Rate Accelerations of Bromination Reactions with NaBr and H2O2 via the Addition of Catalytic Quantities of Diaryl Ditellurides

30-09-2014 | Eduardo E. Alberto; Lisa M. Muller; Michael R. Detty, Organometallics, 2014

Diaryl ditellurides were oxidized in situ to give aryltellurinic acids, which catalyzed the oxidation of NaBr with H2O2 in buffered aqueous solutions. The aryltellurinic acids were slowly oxidized under the reaction conditions to the corresponding telluronic acids, which did not catalyze ...


Water-Soluble-Phosphines-Assisted Cobalt Separation in Cobalt-Catalyzed Hydroformylation

13-09-2013 | László T. Mika; László Orha; Eddie van Driessche; Ron Garton; Katalin Zih-Perényi; István T. Horváth, Organometallics, 2013

The hydroformylation of octene-1 and the removal of Co2(CO)8 and HCo(CO)4 from the reaction products including commercial C9 OXO-product were studied under biphasic conditions using an aqueous solution of different electron-donating sulfonated phosphine RnP(C6H4-m-SO3Na)2 (n = 0, 1, 2; R = Me, ...


Tetrahedral [HnPt4(CO)4(P∧P)2]n+ (n = 1, 2; P∧P = CH2═C(PPh2)2) Cationic Mono- and Dihydrido Carbonyl Clusters Obtained by Protonation of the Neutral Pt4(CO)4(P∧P)2

11-09-2013 | Iacopo Ciabatti; Cristina Femoni; Maria Carmela Iapalucci; Giuliano Longoni; Stefano Zacchini, Organometallics, 2013

The reaction of [Pt12(CO)24]2– with CH2═C(PPh2)2 (P∧P) results in the neutral tetrahedral cluster Pt4(CO)4(P∧P)2. This reacts with strong acids such as HBF4 to afford, first, the [HPt4(CO)4(P∧P)2]+ monohydride monocation and, then, the [H2Pt4(CO)4(P∧P)2]2+ dihydride dication. The three clusters ...
