Kinetic, spectroscopic and computational studies examining a palladium-catalyzed imidoylative coupling highlight the dual role of isocyanides as both substrates and ligands for this class of transformations. The synthesis of secondary amides from aryl halides and water is presented as a case study. The kinetics of the oxidative addition of ArI with RNC-ligated Pd0species have been studied and the resulting imidoyl complex [(ArC=NR)Pd(CNR)2I] (Ar=4-F-C6H4, R=tBu) has been isolated and characterized by X-ray diffraction. The unprecedented ability of this RNC-ligated imidoyl-Pd complex to undergo reductive elimination at room temperature to give the amide in the presence of water and an F?/HF buffer is demonstrated. Its behavior in solution has also been characterized, revealing an unexpected strong tendency to give cationic complexes, and notably [(ArC=NR)Pd(CNR)3]+with excess isocyanide and [(ArC=NR)Pd(PP)(CNR)]+with bidentate phosphines (PP). These species may be responsible for catalyst deactivation and side-reactions. Ab initio calculations performed at the DFT level allowed us to rationalize the multiple roles of RNC in the different steps of the catalytic cycle.

Four three-coordinate arylpalladium amido complexes with a single hindered phosphine were isolated and structurally characterized. Each possessed a T-shaped geometry. Several of these complexes possessed true three-coordinate structures that lacked any additional coordination by ligand C-H bonds. All of the three-coordinate complexes underwent reductive elimination to form the corresponding triarylamine. A comparison of the rate of reaction of the three-coordinate compounds demonstrated that the rate of elimination from the pentaphenylferrocenyl di-tert-butylphosphine complex were the fastest. A comparison of the rates of reactions between three-coordinate and four-coordinate complexes showed that the rates were much faster from the three-coordinate complexes. Copyright

Pyrophosphate (PPi) is involved in lots of anabolism and bioenergetic processes in organisms and possesses important biological functions so that its detection is very significant. Here, we developed a selective fluorometric detection method for PPi with a copper(II) complex of 2,6-bis(2-benzimidazolyl)pyridine (bbimp), and then applied it to the detection of bacterial alarmone ppGpp. bbimp has the fluorescence emission at 395nm, but the bbimp-Cu2+ complex is hardly fluorescent because the intrinsic fluorescence of bbimp is effectively quenched by Cu2+. With the addition of PPi, however, the fluorescence emission of bbimp turns on with a 2nm red-shift, and has a linear relationship with PPi in the range of 3-90mumol/L. This method has good selectivity for PPi over other anions especially those phosphate-containing anions such as ATP, UTP, CTP, GTP, GDP, and PO43-.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), molecular formula is C34H28Cl2FeP2Pd

A new process for converting secondary amines into N,N,N?,N?- tetraalkyloxamides under CO pressure, catalyzed by homogeneous palladium complexes in the presence of 1,4-dichloro-2-butene (DCB) as an oxidant, has been developed. The mechanism of the oxidative double-carbonylation process, consisting of the oxidation of Pd(0) to Pd(11) with DCB through a beta-chloride elimination of the eta3-(chloromethyl) allylpalladiuni(11) intermediate, the formation of mono- and bis(carbamoyl)palladium species, and a reductive elimination of the two carbamoyl ligands, is proposed based on studies of the behavior of carbamoylpalladium complexes. When primary amines are employed with DCB as the oxidant, N,N?-dialkyloxamide is catalytically produced, whereas urea is exclusively produced when iodine is used as the oxidant. The reaction of an N-monopropylcarbamoylpalladium complex with propylamine under CO gave N,N?-dipropylurea, whereas a treatment with diethylamine yielded unsymmetrical N,N-diethyl-N?-propylurea, implying the intermediate formation of propyl isocyanate that is converted into the urea upon a reaction with the added amine. A kinetic study on the reaction of chloro-N- propylcarbamoylpalladium with triethylamine suggested a process proceeding through a base-promoted dcprolonalion of the N-monoalkylcarbamoyl ligand to form propyl isocyanate.

The activation of the inert C-O bonds in mesylates through the use of a new class of imidazolyl phosphines allows the decarboxylative coupling of aryl mesylates as well as polysubstituted alkenyl mesylates. Variation of the ligands leads to two complementary methods providing the corresponding biaryls and polysubstituted olefins in good yields. Copyright

Two kinds of A1-(D-A2)3-type (A1, A2: acceptor, D: donor) triazine-based star-shaped acceptors, TzTPT-INCN and TzCDT-INCN, are reported to show strong face-on orientation with J- to H-type packing structural transformation with thermal annealing (TA) treatments. TA of the thin films of both acceptors mainly leads to the formation of thermodynamically more stable H-type packing with enhanced hypsochromic absorption peaks in the UV?vis spectra. The results agree well with calculations based on time-dependent density-functional theory. To determine the optimum TA conditions for fabricating organic photovoltaic (OPV) devices, in-depth studies are conducted through in situ grazing incidence wide-angle X-ray scattering to analyze changes in the molecular packing structure with respect to the TA temperature employed. Sequential deposition bilayer OPV devices are fabricated by combining the two acceptors with a donor polymer PBDB-T. Although the electron mobilities and power conversion efficiencies are improved slightly (PBDB-T/TzTPT-INCN: 4.26 to 4.65%, PBDB-T/TzCDT-INCN: 6.58 to 7.18%) via transformation from a J-dominant to H-dominant morphology, the differences are not significant. Similar charge transport characteristics are observed for both the H- and J-type stacked structures. The study can be used to better understand the modification of molecular packing via the manipulation of molecular design and to determine the correlation between packing structures and electrical properties.
