A process is described for the synthesis of a cationic [rhodium diolefin phosphorus ligand] complex comprising the steps of: (a) reacting a rhodium-diolefin-1,3-diketonate and an acid in a ketone solvent, (b) adding a stabilising olefin to form a stabilised cationic rhodium compound, and (c) mixing a phosphorus ligand with the solution of the stabilised cationic rhodium compound to form a solution of the cationic [rhodium diolefin phosphorus ligand] complex. The solution may be used directly or the complex recovered. In one embodiment, the solution may be combined with a co-solvent and the ketone removed to give a new catalyst solution, from which the complex may be recovered.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C36H28OP2, you can also check out more blogs about166330-10-5

Rh(I) and Rh(III) complexes of tricyclopentylphosphine (PCyp3), or its dehydrogenated variant PCyp2(eta2-C 5H7), partnered with wide-bite-angle chelating diphosphine ligands DPEphos and Xantphos have been prepared and characterized in solution and the solid state with the aim of studying their potential for reversible dehydrogenation of the PCyp3 ligand. The complexes fac-[Rh(kappa3-P,O,P-L){PCyp2(eta2-C 5H7)}][BArF4] (L = DPEphos, Xantphos) show pseudo-trigonal-bipyramidal structures in which the dehydrogenated phosphine alkene ligand acts in a chelating manner. Addition of H2 to fac-[Rh(kappa3-P,O,P-DPEphos){PCyp 2(eta2-C5H7)}][BAr F4] resulted in an equilibrium mixture of hydride and hydride-dihydrogen complexes, fac-[Rh(kappa3-P,O,P-DPEphos)(H) 2(PCyp3)][BArF4] and [Rh(kappa2-P,P-DPEphos)(eta2-H2)(H) 2(PCyp3)][BArF4], in which the DPEphos acts as a hemilabile ligand. For the more rigid Xantphos ligand two dihydride isomers, fac-[Rh(kappa3-P,O,P-Xantphos)(H) 2(PCyp3)][BArF4] and mer-[Rh(kappa3-P,O,P-Xantphos)(H)2(PCyp 3)][BArF4], are formed, which are also in equilibrium with one another. A van?t Hoff analysis of this mixture shows that enthalpically there is very little difference between the two geometries for this system, with the driving force for the preferred fac-geometry being entropic. Addition of MeCN to these hydrido complexes results in the central oxygen atom being displaced to form [Rh(kappa2-P,P-L)(PCyp 3)(H)2(MeCN)][BArF4], while removal of H2 from the hydrido complexes (under vacuum or on addition of a hydrogen acceptor) forms the Rh(I) complexes [Rh(kappa3-P,O,P-L) (PCyp3)][BArF4], which are characterized as having square-planar geometries with meridonial coordination of the respective chelating phosphines. Dehydrogenation of the PCyp3 ligand in these complexes to re-form the phosphine-alkene ligands does not occur, even under forcing conditions.

The preparation, structure, dynamic behavior in solution, and reactivity of polyhydride complexes of platinum group metals, described during the last three decades, are contextualized from both organometallic and coordination chemistry points of view. These compounds, which contain dihydrogen, elongated dihydrogen, compressed dihydride, and classical dihydride ligands promote the activation of B-H, C-H, Si-H, N-H, O-H, C-C, C-N, and C-F, among other sigma-bonds. In this review, it is shown that, unlike other more mature areas, the chemistry of polyhydrides offers new exciting conceptual challenges and at the same time the possibility of interacting with other fields including the conversion and storage of regenerative energy, organic synthetic chemistry, drug design, and material science. This wide range of possible interactions foresees promising advances in the near future.

Unprecedented chemoselective reductions of phosphine oxides to phosphines proceed smoothly in the presence of catalytic amounts of specific Br°nsted acids. By utilizing inexpensive silanes, e.g., PMHS or (EtO)2MeSiH, other reducible functional groups such as ketones, aldehydes, olefins, nitriles, and esters are well-tolerated under optimized conditions.

The diimine compound 1-[(2′,3′,4′,5′-tetraphenylbiphenyl-4-yl)methyl]-2- (pyridin-2-yl)-1H-benzo[d]imidazole (Ph6PyMz) has been designed and synthesized in order to prepare [Cu(Ph6PyMz)(DPEphos)]BF4 {DPEphos = bis[2-(diphenylphosphanyl)phenyl] ether} and [RePh 6PyMz(CO)3Br]. The molecular structures of [Cu(Ph 6PyMz)(DPEphos)]BF4 and [RePh6PyMz(CO) 3Br] were determined by single-crystal X-ray diffraction and IR spectroscopy, and their properties were systematically studied by thermal-stability analyses, photophysical analyses, and electrochemistry. It was found that [Cu(Ph6PyMz)(DPEphos)]BF4 and [RePh 6PyMz(CO)3Br] mainly give triplet-ligand-to-ligand charge-transfer transition emission in CH2Cl2 solution and pure triplet-metal-to-ligand charge-transfer transition emission in the solid state. The different photophysical behaviors of [Cu(Ph6PyMz)(DPEphos) ]BF4 and [RePh6PyMz(CO)3Br] in different states has been attributed to solvent effects and their higher freedom in CH 2Cl2 solution. The energy levels of the highest-occupied and lowest-unoccupied molecular orbitals were measured to be -5.76 and -3.11 eV for [Cu(Ph6PyMz)(DPEphos)]BF4 and -5.69 and -3.42 eV for [RePh6PyMz(CO)3Br], respectively. Finally, the ground-state geometrical structures and the UV/Vis absorption spectra in CH 2Cl2 solution were theoretically simulated for [Cu(Ph 6PyMz)(DPEphos)]BF4 and [RePh6PyMz(CO) 3Br]. We have used the diimine Ph6PyMz to synthesize the two transition-metal complexes [Cu(Ph6PyMz)(DPEphos)]BF4 and [RePh6PyMz(CO)3Br], which mainly gave 3LLCT emission in CH2Cl2 solution and pure 3MLCT emission in the solid state. This different photophysical behavior has mainly been attributed to the higher freedom of Ph6PyMz. Copyright

The methoxycarbonylation reaction provides a route to the synthesis of esters from medium-chain alkenes that may be used as fuel supplements. However, the known productive catalytic systems are expensive and/or unstable at elevated temperatures. Most of the data available on the methoxycarbonylation of alkenes is derived from ethylene and styrene as substrates. To broaden the scope, we conducted a comparative study of a range of phosphine ligands under comparable conditions for the methoxycarbonylation of 1-octene. The results demonstrate that a number of ligand structural motifs facilitate the process effectually. Furthermore, the critical importance of alkene isomerization and the acid/ligand and Pd/ligand ratios are presented.

The borrowing hydrogen (BH) principle, also called hydrogen auto-transfer, is a powerful approach which combines transfer hydrogenation (avoiding the direct use of molecular hydrogen) with one or more intermediate reactions to synthesize more complex molecules without the need for tedious separation or isolation processes. The strategy which usually relies on three steps, (i) dehydrogenation, (ii) intermediate reaction, and (iii) hydrogenation, is an excellent and well-recognized process from the synthetic, economic, and environmental point of view. In this context, the objective of the present review is to give a global overview on the topic starting from those contributions published prior to the emergence of the BH concept to the most recent and current research under the term of BH catalysis. Two main subareas of the topic (homogeneous and heterogeneous catalysis) have been identified, from which three subheadings based on the source of the electrophile (alkanes, alcohols, and amines) have been considered. Then the type of bond being formed (carbon-carbon and carbon heteroatom) has been taken into account to end-up with the intermediate reaction working in tandem with the metal-catalyzed hydrogenation/dehydrogenation step. The review has been completed with the more recent advances in asymmetric catalysis using the BH strategy.

Neutral mononuclear Cu(I) complexes based on 2,2?-dipyridylamine (dpa), formulated as [Cu(dpa)X(PPh3)] (X = Cl (A4), Br (A5), I (A6)), monocationic mononuclear Cu(I) complexes with counterion BF4-, i.e. [Cu(dpa)(PPh3)2](BF4) (A1), Cu(dpa)(DPEphos)(BF4) (A2) and [Cu(dpa)(Binap)](BF4) (A3), where DPEphos = bis [2-(diphenylphosphino) phenyl] ether, Binap = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl, have been prepared and characterized by 1H NMR, mass spectroscopy and single-crystal X-ray analyses. Their photophysical properties in both CH2Cl2 solution and PMMA (poly(methyl methacrylate)) film have been investigated. All the complexes display a typical metal-to-ligand charge transfer absorption band in the region of 350-400 nm, and a broad and featureless luminescence at room temperature. Specifically, their emission maxima vary from 494 to 562 nm in the PMMA films due to the different electronic characteristics of the auxiliary ligands. Additionally, the thermogravimetric analysis shows that those complexes chelated with diphosphine ligands have a higher thermal stability than those with triphenylphosphine or halides ligands.
