Mechanistic Insights on Pd/Cu-Catalyzed Dehydrogenative Coupling of Dimethyl Phthalate

Despite its industrial importance, very limited mechanistic information on the dehydrogenative coupling of dimethyl phthalate has been reported. Herein we report the detailed mechanism for dehydrogenative coupling of dimethyl phthalate catalyzed by [Pd(OAc)2]/[Cu(OAc)2]/1,10-phenanthroline¡¤H2O (phen¡¤H2O). The solution-phase analysis of the catalytic system by XANES shows the active species to be Pd(II), and EXAFS supports the formation of an (acetato)(dimethyl phthalyl)(phen)palladium(II) complex from [Pd(OAc)2]. A formation pathway of tetramethyl 3,3?,4,4?-biphenyltetracarboxylate via disproportionation of independently prepared [Pd(OAc){C6H3(CO2Me)2-3,4}(phen)] is observed with regeneration of [Pd(OAc)2(phen)].

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Quality Control of Bis(acetylacetone)copper, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13395-16-9, in my other articles.

All-solution-processed high-performance quantum dot light emitting devices employing an inorganic thiocyanate as hole injection layer

We report here the all-solution-processed, high-efficiency quantum dot light emitting diode (QLED) employing inorganic copper (I) thiocyanate (CuSCN) as hole injection layer. In comparison with the widely used injection material of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS), the hole injection into the QD layer is significantly improved, allowing low turn-on voltage, high luminance and efficiency. By optimizing the multilayer structure and synergistically balancing the carrier injection, the resulting QLEDs exhibit high performance with the maximum current efficiency of 52.4 cd/A and external quantum efficiency of 12.0% for green device, 17.0 cd/A and 16.2% for red device. These results indicate that CuSCN is a reliable hole transport materials for low-cost, high-efficiency QLED devices.

Copper-Catalyzed Cross-Coupling of Silicon Pronucleophiles with Unactivated Alkyl Electrophiles Coupled with Radical Cyclization

A copper-catalyzed C(sp3)-Si cross-coupling of aliphatic C(sp3)-I electrophiles using a Si-B reagent as the silicon pronucleophile is reported. The reaction involves an alkyl radical intermediate that also engages in 5-exo-trig ring closures onto pendant alkenes prior to the terminating C(sp3)-Si bond formation. Several Ueno-Stork-type precursors cyclized with excellent diastereocontrol in good yields. The base-mediated release of the silicon nucleophile and the copper-catalyzed radical process are analyzed by quantum-chemical calculations, leading to a full mechanistic picture.

Effect of surface treatment of the support on co oxidation over carbon-supported Wacker-type catalysts

The impact of surface treatment of the support on the oxidation of CO over carbon-supported Wacker-type catalyts was studied. This study focused on the effect of the chemical properties of activated carbon on CO oxidation over supported PdCl2-CuCl2 and PdCl2-CuCl2-Cu(NO)32 catalyts. The surface of active carbon used to prepare supported Wacker-type catalysts was enriched with carboxylic acid and carbonyl groups by pretreating with HNO3 or adding Cu(NO3)2 as a supplementary copper precursor. These surface groups improved the hydrophilicity and facilitated the formation of an active copper phase (Cu2Cl(OH)3). The effects were stronger, particularly on the formation of Cu2Cl(OH)3, when Cu(NO3)2 was combined with CuCl2 as catalyst precursors. The acceleration of CO oxidation can be attributed to the formation of the active copper phase and the improved hydrophilicity.

Extended supramolecular structures derived from metal pseudohalides and 4,4?-bipyridinium derivative: Synthesis, structures and optical properties

Four novel extended supramolecular structures based on pseudohalides (SCN) and the flexible cationic ligand 1,4-bis(4,4?-bipyridinium)butane ditetrafluoroborate (bbpyb), namely [bbpyb][Hg(SCN)4] (1), [Cu2(bbpyb)(SCN)4]n (2), [Ag2(bbpyb)(SCN)4]n (3) and [Cu6(bbpyb)(SCN)8]n (4) have been solvothermally synthesized and characterized by IR spectroscopy, thermal gravimetric analysis(TGA), PXRD, UV-Vis diffuse reflectance spectra and single-crystal X-ray diffraction in the solid state. Compound 1 is a 0D supramolecular structure consisted of one linear cationic ligand bbpyb2+ and inorganic mononuclear anion [Hg(SCN)4]2-. Compounds 2 and 3 exhibit infinite two-dimensional anionic architecture, which represent the same (6,3) topology. In compound 4, the cationic ligand bbpyb2+ bridge [Cu6(SCN)8] cluster unit to generate a 3D coordination framework. The structural diversities show that the pseudohalides (SCN) and cationic ligand should very likely be excellent candidates to construct higher dimensional extend supramolecular architectures. In addition, the optical band gap and photocatalytic properties of compounds 1-4 were also investigated.

Copper-catalyzed cyclopropanation of 1,2,3,4-tetrahydropyridin-2-ones with diazoacetates: A facile and stereoselective synthesis of 3-oxo-2-azabicyclo [4.1.0] heptanes

The reactions of a series of 1,2,3,4-tetrahydropyridin-2-ones (1) with diazoacetates (2) in the presence of copper-bronze catalyst yielded exclusively 3-oxo-2-azabicyclo [4.1.0] heptanes (3 and 4) in excellent yields with high exo-selectivity. Tetrahydropyridin-2-ones (1) with N-alkyl substituents were found to be more reactive than N-aryl substitutents. Among the various copper catalysts studied, copper(II) triflate was found to be the best catalyst while rhodium chloride, ruthenium chloride did not catalyze the reaction. The application of ultrasonic radiation enhanced the reaction rate and allowed the reactions to be conducted at room temperature.

2-Picolinic acid and benzoic acid from di-2-pyridyl ketone and acetophenone: A case of two copper catalysed Baeyer-Villiger rearrangements?

The synthesis and crystal structure elucidation of two novel polymeric copper(II) complexes has led us to propose a mechanism for the formation of 2-picolinic acid (pic) from di-2-pyridyl ketone (dpk) and benzoic acid from acetophenone. During studies into the interaction of copper ions with the dpk-acetophenone system, two complexes Na2(NCS)2(H 2O)[Cu(pic)2] (1) and Na2(H2O) 2[Cu(pic)2(NCS)2] (2) which contain pic coordinated to copper were isolated. The occurrence of (1) and (2) has led us to consider the Baeyer-Villiger rearrangement as a possible mechanism for the formation of (1) and (2).
