3,6-Di-tert-butyl-o-benzosemiquinone complexes of copper(I) with bidentate bis(diphenylphosphine) ligands. Synthesis, structures, and properties

New mononuclear 3,6-di-tert-butyl-o-benzosemiquinone complexes of copper(I) with bis(diphenylphosphine) ligands were synthesized: (DBSQ)Cu(dppe) (1) (DBSQ = 3,6-ditert-butyl-o-benzosemiquinone and dppe = 1,2-bis(diphenylphosphino)ethane), (DBSQ)Cu(dppp) (2) (dppp = 1,3-bis(diphenylphosphino)propane), (DBSQ)Cu(dppn) (3) (dppn = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl), and (DBSQ)Cu(dppfc) (4) (dppfc = 1,1?-bis(diphenylphosphino)ferrocene). The compositions and structures of complexes 1-4 were characterized by elemental analysis and electronic absorption, IR, and ESR spectroscopy. The molecular structures of complexes 3 and 4 were established by X-ray diffraction analysis. The reactions of elimination and replacement of neutral ligands in the coordination sphere of the complexes were studied by ESR spectroscopy.

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.Quality Control of: 1,1-Bis(diphenylphosphino)ferrocene, you can also check out more blogs about12150-46-8

A four-coordinate Cu(I)?N-heterocyclic carbene complex: Synthesis, structure, properties, and application in amination for the synthesis of 1-(2-N-heteroaryl)-1H-pyrazoles

A new luminescent, cationic, heteroleptic, four-coordinate Cu(I)?N-heterocyclic carbene complex [Cu(Br-Pyim)(POP)](PF6) is successfully prepared and characterized, where Br-Pyim and POP are 1-(6-bromopyridin-2-yl)imidazole-3-benzyl-2-ylidene and bis[2-(diphenylphosphino)phenyl]ether, respectively. Its detailed structure is determined by single-crystal X-ray analysis. It exists as a crystalline powder at room temperature and exhibits bright yellow-green emission. The use of the Cu(I)?N-heterocyclic carbene complex as a catalyst for amination reactions is also investigated and is found to be very efficient for the amination of 2-N-heteroaryl chlorides with pyrazoles, giving the desired substituted 1-(2-N-heteroaryl)-1H-pyrazoles in good yields.

Synthetic studies of permethylcyclopentadienyl ruthenium(II) complexes involving dppf, (¡À) -BINAP and (¡À) -DIOP ligands

1,1?-Bis(diphenylphosphino)ferrocene (dppf) reacted with RuCl(Ph3P)2Cp* to give RuCl(dppf)Cp* in good yield. The complex reacted with AgBF4 in acetonitrile to give [Ru(CH3CN) (dppf)Cp*]BF4 quantitatively and in acetone to give [Ru(eta2-O2) (dppf)Cp*]BF4 in good yield. The structure of the latter was determined by X-ray analysis. (¡À)-BINAP and (¡À)-DIOP were reacted with [RuCl2Cp*]n/Zn to give RuCl[(¡À)-BINAP]Cp* and RuCl[(¡À)-DIOP]Cp*, respectively, in moderate yields. They reacted with phenylacetylene in the presence of NH4PF6 to afford the corresponding RuII phenylacetylide complexes. The asymmetric condensation of phenylacetylene with allyl alcohol in the presence of these diphosphine complexes was unsuccessful.

A theoretical perspective on charge transfer in photocatalysis. The example of Ir-based systems

Research on photocatalytic water splitting is a rapidly developing area, holding the promise to transform solar energy into chemical form that can be stored and reused on demand. Existing photocatalytic systems or dye-sensitized solar cells exploit a charge separation mechanism occurring upon photoexcitation. Along with the numerous experimental studies, theoretical simulations are performed to assist the interpretation of experimental data and the rational design of new environmentally benign systems. However, the accuracy of the theoretical results should be judged carefully since charge transfer processes represent a challenge at least for the widely used time-dependent density functional theory.In this review, we address the state-of-the-art of homogeneous photocatalysis based on noble metal photosensitizers from the quantum chemistry viewpoint. Exemplarily, we focus on a system with an iridium(III) photosensitizer, triethylamine as sacrificial reductant, and an iron carbonyl based water reduction catalyst. In addition, we consider the possible venues of improving the efficiency of solar light collection by introducing silver nanoparticles into the system. The applicability of various single- and multi-reference wave-function methods and especially of the optimally tuned long-range corrected density functional theory for the prediction of electronic spectra and intermolecular charge transfer probabilities is discussed.

Method of preparing 4-R-substituted 4-demethoxydaunorubicin

A method of synthesizing 4-R-substituted anthracyclines and their corresponding salts from 4-demethyldaunorubicin includes the steps of treating 4-demethyldaunorubicin with a sulfonylating agent to form 4-demethyl-4-sulfonyl-R3-daunorubicin. 4-Demethyl-4-R3-sulfonyl-daunorubicin is then subject to a reducing agent in the presence of a transition metal catalyst in a temperature range of about 30 C. to about 100 C. in a polar aprotic solvent in an inert atmosphere. Protected 4-demethoxy-4-R-daunomycin then undergoes hydrolysis in a basic solution to form the 4-R-substituted anthracyclines. The novel method lacks the step of forming a stereospecific glycoside bond between aglycone and aminoglycoside. The method also increases the yield of the final product up to 30 to 40%.
