This review is concerned with data on the composition and structure of intermediate paramagnetic cobalt and nickel compounds in Ziegler-type metal complex catalysts. The problem of reactivity of the intermediate compounds is briefly outlined. General regularities are revealed for the mechanism of formation of the metal complex catalysts. Particular emphasis is made on the structure of intermediates whose EPR spectra explicitly exhibit the effects of vibronic interactions. Vibronic effects are shown to play an important role in the realization of geometric configuration for structures with the pseudodegenerate electronic state. (C) 2000 Elsevier Science B.V.

Rh(i)-Catalyzed decarbonylative direct C-H bond vinylation and dienylation of arenes with readily available acrylic acid and (E)-penta-2,4-dienoic acid under chelation assistance have been developed for the first time. A significant effect of the ligand on the reactivity was observed with the bidentate phosphine ligand being optimal. This protocol was efficient under oxidant-free conditions to access synthetically valuable styrenes and 1-aryl-1,3-butadienes in high yields with a broad substrate scope and good functionality tolerance.

Background: Photoluminescent materials have been used for diverse applications in the fields of science and engineering, such as optical storage, biological labeling, noninvasive imaging, solid-state lasers, light-emitting diodes, theranostics/theragnostics, up-conversion lasers, solar cells, spectrum modifiers, photodynamic therapy remote controllers, optical waveguide amplifiers and temperature sensors. Nanosized luminescent materials could be ideal candidates in these applica-tions. Objective: This review is to present a brief overview of photoluminescent nanofibers obtained through electrospinning and their emission characteristics. Methods: To prepare bulk-scale nanosized materials efficiently and cost-effectively, electrospinning is a widely used technique. By the electrospinning method, a sufficiently high direct-current voltage is applied to a polymer solution or melt; and at a certain critical point when the electrostatic force overcomes the surface tension, the droplet is stretched to form nanofibers. Polymer solutions or melts with a high degree of molecular cohesion due to intermolecular interactions are the feedstock. Sub-sequent calcination in air or specific gas may be required to remove the organic elements to obtain the desired composition. Results: The luminescent nanofibers are classified based on the composition, structure, and synthesis material. The photoluminescent emission characteristics of the nanofibers reveal intriguing features such as polarized emission, energy transfer, fluorescent quenching, and sensing. An overview of the process, controlling parameters and techniques associated with electrospinning of organic, inorganic and composite nanofibers are discussed in detail. The scope and potential applications of these luminescent fibers also conversed. Conclusion: The electrospinning process is a matured technique to produce nanofibers on a large scale. Organic nanofibers have exhibited superior fluorescent emissions for waveguides, LEDs and lasing devices, and inorganic nanofibers for high-end sensors, scintillators, and catalysts. Multi-functionalities can be achieved for photovoltaics, sensing, drug delivery, magnetism, catalysis, and so on. The potential of these nanofibers can be extended but not limited to smart clothing, tissue engineering, energy harvesting, energy storage, communication, safe data storage, etc. and it is anticipated that in the near future, luminescent nanofibers will find many more applications in diverse scientific disciplines.

A series of the new chiral BINOL-based phosphite P,N-hybrid ligands was prepared. The coordination behavior of all the ligands was studied and the neutral complexes [Rh(CO)Cl(P N)] were synthesized in order to characterize a degree of the electronic non-symmetry of donating centers. Also the neutral and cationic complexes cis-[PdCl2(eta2-P N=)], cis-[PdCl2(eta1-P N=)2], cis-[PdCl(eta2-P N=) (eta1-P N=)]+Cl-,[Pd(allyl)(eta2-P N=)]+X- (X- = Cl-, BF4-) were obtained and characterized. The new P,N-hybrid ligands gave up to 81% ee in the enantioselective Pd-catalyzed alkylation of 3-penten-2-yl carbonate by dimethyl malonate and up to 60% ee in the Rh-catalyzed hydrosilylation of acetophenone and acetylferrocene by diphenylsilane.

The trans bromide of 2,2-dibromo-1-(2,4,6-tri-t-butylphenyl)-1-phosphaethene (Mes*P=CBr2; Mes=2,4,6-tBu3C6H2) can be successfully substituted with an aryl group by using a palladium version of the Kumada-Tamao-Corriu cross-coupling process. Predominant formation of the 2-aryl-2-bromo-1-phosphaethene [(Z)-Mes*P=C(Br)Ar] required suitable conditions including optimization of the ancillary phosphine ligand, thereby retarding the dual elimination of bromides leading to phosphaalkyne (Mes*C?P). The 2-aryl-2-bromo-1-phosphaethenes hold promise as versatile synthons for functional pi-conjugated molecules, and stereospecific transformations of the bromine atom by halogen-metal exchange and palladium-catalyzed arylations were demonstrated.

Application of 13991-08-7, An article , which mentions 13991-08-7, molecular formula is C30H24P2. The compound – 1,2-Bis(diphenylphosphino)benzene played an important role in people’s production and life.

The ligand trihydrido(3,5-diphenylpyrazol-1-yl)borate([MpPh2]-) has been synthesized from 3,5-diphenylpyrazole and sodium borohydride in N,N-dimethylformamide. By using this ligand, three phosphane-stabilized copper(I) complexes [Cu(MpPh2)(L2)] [L2 = (PPh3)2, 1,2-bis(diphenylphosphanyl)ethane (dppe), or 1,2-bis(diphenylphosphanyl)benzene (dppbz)] were synthesized. The complexes were characterized by multinuclear NMR spectroscopy, IR spectroscopy, and X-ray crystallography. The crystal structures of these complexes show that the copper ions are in trigonal-pyramidal geometries with the apical position formed by agostic Cu-H interactions between the CuI center and one of the hydride atoms of the borate ligand. Complexes [Cu(MpPh2)(PPh3)2] and [Cu(MpPh2)(dppbz)] are mononuclear, whereas complex [Cu2(MpPh2)2(mu-dppe)2] is dinuclear with bridging dppe ligands. In the solid state, fluorescent emissions are observed in [Cu(MpPh2)(PPh3)2] and [Cu2(MpPh2)2(mu-dppe)2] but not in [Cu(MpPh2)(dppbz)], which exhibits bright cyan phosphorescence at room temperature that shifts to green when the sample is cooled to 77 K. The phosphorescence of [Cu(MpPh2)(dppbz)] is attributed to mixed interligand and metal-to-ligand charge transfer 3(MLCT + pi-pi) excited states.

In sharp contrast to tetraphenyldiphosphine, which does not add to carbon?carbon double bonds efficiently, its monoxide, [Ph2P(O)PPh2] can engage in a radical addition to various alkenes, thus affording the corresponding 1-phosphinyl-2-phosphinoalkanes regioselectively, and they can be converted into their sulfides by treatment with elemental sulfur. The phosphinylphosphination proceeds by the homolytic cleavage of the PV(O)?PIIIsingle bond of Ph2P(O)PPh2, followed by selective attack of the phosphinyl radical at the terminal position of the alkenes, and selective trapping of the resulting carbon radical by the phosphino group. Furthermore, the phosphinylphosphination product could be converted directly into its platinum complex with a hemilabile P,O chelation.
