A series of cationic (diphosphine)palladium(II) complexes have been prepared and fully characterized, including two crystal structures. These complexes were evaluated as catalysts for the hydroamination of acyclic alkenes. The reactivity of the catalysts is dependent on the nature of the diphosphine ligand and the substituents on the amine and alkene substrates.

“Chemical Equation Represented” With air as the oxidant, terminal alkynes can be directly cross-coupled with alkylzinc reagents in the presence of a Pd catalyst at room temperature. CO was found to be critical in gaining high chemical yields and selectivities. A wide range of alkynes and alkylzinc reagents were tested, and good to excellent yields were obtained. Copyright

Alternating copolymers, poly(2,5-bis(2-decyltetradecyl)-3,6-di(furan-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione-b-(E)-1,2-di(furan-2-yl)ethene) (P(FDPP-FVF)) and poly(2,5-bis(2-decyltetradecyl)-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione-b-(E)-1,2-di(furan-2-yl)ethene) (P(ThDPP-FVF)), composed of (E)-1,2-di(furan-2-yl)ethene and diketopyrrolopyrrole, were synthesized and studied for solution-processable organic field effect transistors (OFETs). Highest hole mobilities of 0.45 and 0.24 cm2 V-1 s-1 were measured for P(FDPP-FVF) and P(ThDPP-FVF), respectively, in bottom gate-bottom contact transistor devices. Atomic force microscopy and grazing incidence X-ray diffraction experiments were employed to investigate the crystallinity and morphology for the spin-cast polymer films. It is noteworthy that the thermally annealed P(FDPP-FVF) film exhibited higher crystallinity and small pi-stacking distance of 3.47 A. Moreover, considering the easy synthesis from renewable furfural and better performance of P(FDPP-FVF), our results provide an alternative design strategy for the synthesis of solution-based semiconducting polymers from renewable furan derivatives for OFETs.

Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C51H42O3Pd2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52409-22-0

A series of low band gap polymers composed of benzotriazole and benzo[1,2-b:4,5-b?]dithiophene derivatives were synthesized using a Stille cross-coupling reaction for use in organic photovoltaic devices. Linear or branched alkyl groups were incorporated into the benzothiazole-based accepting monomer part, and alkoxy or alkylthiophene groups were introduced to benzo[1,2-b:4,5-b?]dithiophene-based donating monomer part. Changes in photo-physical properties of the polymers by the structural modification of the donor-acceptor type low band gap polymers were investigated. The synthesized polymers were soluble in common organic solvents, and the resulting polymer solutions could be used to form smooth and uniform thin films by spin-casting. The synthesized polymers were found to exhibit good thermal stability, losing less than 5% of their weight upon heating to approximately 300C. The intra-molecular charge transfer interaction between the electron donating and electron accepting blocks in the polymeric backbone induced a broad absorption from 300 to 650 nm. The optical band gap energies of the polymers were measured to be 2.03-1.90 eV depending on the polymer structure. Solution-processed field-effect transistors were fabricated and characterized using the polymers as p-type channel materials. Bulk hetero-junction photovoltaic devices were fabricated using the polymers with [6,6]-phenyl C71-butyric acid methyl ester (PC71BM) as the electron acceptor. One of the fabricated device showed the maximum power conversion efficiency of 3.20% under AM 1.5 G (100 mW/cm2) conditions.

The reaction of [Pd(dtbpf)Cl2] (dtbpf = 1,1?-bis(di-tert- butylphosphino)ferrocene) with a chemical oxidant led unexpectedly to the formation of [Pd(dtbpf)Cl]+. Further study found that a variety of reagents could be used to abstract a chloride ligand from [Pd(dtbpf)Cl 2] to yield [Pd(dtbpf)Cl]+. The solid-state structure suggests the formation of an Fe-Pd interaction. The presence of the bulky tert-butyl groups is essential, as similar reactions with [Pd(PP)Cl2] (PP = other 1,1?-bis(phosphino)ferrocene ligands) results in the formation of [Pd(PP)(mu-Cl)]22+. The analogous platinum compounds have also been investigated and appear to behave in a similar manner. Similar compounds of the type [M?(PP)(PR3)]2+ (M? = Pd, Pt, R = Ph, Me) have been prepared, and a metal-metal interaction has also been observed. Steric and electronic effects dictate the formation of these compounds. X-ray crystal structures were obtained for eight of these compounds and were used as the basis for a computational analysis of the metal-metal interaction. DFT analysis indicates the presence of a weak, noncovalent interaction between the two metal centers. The electrochemical properties of these compounds were examined by cyclic voltammetry and typically show one oxidative wave and either one two-electron or two one-electron reductive waves.

A series of diphosphine ligands possessing a barbiturate-binding receptor have been synthesized with the goal of preparing new palladium(0) complexes for the Heck reaction, which position the alkene with respect to the metal center and thereby control the regioselectivity of the insertion step. Some of the diphosphines prepared were found to efficiently form macrocyclic bisphosphine palladium(0) complexes even though a 26-membered cycle is produced. A significant solvent effect for the oxidative addition of the Pd0 complexes with phenyl iodide was noted in the case of one of the diphosphine ligands. This descrepancy may well be accounted for by the ability of the ligand when complexed to Pd0 to possess different conformational preferences in the solvents tested, which influences the bite angle to the metal center. The receptors possessing an isophthaloyl connector bind barbital with affinities corresponding to those of the previously reported open receptors. However, upon complexation with Pd(dba)2, none of the bidentate ligands revealed a capacity to bind barbital, reflecting again the conformational changes that occur upon coordination to Pd0. The new palladium(0) complexes were tested for their ability to promote the Heck reaction between aryl halides and n-butyl acrylate. Whereas all the ligand:Pd0 complexes were found to catalyze this reaction with reactivities similar to triphenylphosphine, in one case a higher reactivity was noted.

A novel approach to produce chiral diaryl sulfoxides from aryl benzyl sulfoxides and aryl bromides via an enantioselective arylation of aryl sulfenate anions is reported. A (JosiPhos)Pd-based catalyst successfully promotes the asymmetric arylation reaction with good functional group compatibility. A wide range of enantioenriched diaryl, aryl heteroaryl, and even diheteroaryl sulfoxides were generated. Many of the sulfoxides prepared herein would be difficult to prepare via classic enantioselective oxidation of sulfides, including Ph(Ph-d5)SO (90% ee, 95% yield). A DFT-based computational study suggested that chiral induction originates from two primary factors: (i) both a kinetic and a thermodynamic preference for oxidative addition that places the bromide trans to the JosiPhos-diarylphosphine moiety and (ii) Curtin-Hammett-type control over the interconversion between O- and S-bound isomers of palladium sulfenate species following rapid interconversion between re- and si-bound transmetalation products, re/si-Pd-OSPh (re/si-PdO-trans).

A palladium-catalyzed enantioselective sequential ring-opening/cross-coupling of cyclobutanones is disclosed that provides chiral indanones bearing C3-quaternary stereocenters. The reaction process involves palladium-catalyzed nucleophilic addition of cyclobutanones and aryl halides, enantioselective beta-carbon elimination, and intermolecular trapping of a transient sigma-alkylpalladium complex with boronic acids. Alternatively, an intramolecular cyclopropanation is realized through C?H bond functionalization in the absence of external coupling reagents, affording chiral cyclopropane-fused-indanones in good yields and enantioselectivity.
