The electrochemistry of 1,1?-bis(dicyclohexylylphosphino)ferrocene (dcpf) was examined in methylene chloride with tetrabutylammonium hexafluorophosphate or tetrabutylammonium tetrakis(pentafluorophenyl)borate as the supporting electrolyte. The oxidation of dcpf is complicated by a follow-up reaction. Seven new complexes containing dcpf and one new compound containing 1,1?-bis(di-tert-butylphosphino)ferrocene (dtbpf) were prepared and characterized. The new complexes were analyzed by cyclic voltammetry and the oxidation of these complexes occurred at a more positive potential than the free ligand. In addition, the X-ray structure of [PdCl2(dcpf)] was determined and compared to other palladium complexes containing bisphosphinometallocene ligands. Five different palladium complexes containing bisphosphinometallocene ligands were examined as catalyst precursors in Buchwald-Hartwig catalysis.

Reaction of [PtCl2(cod)] (cod = cyclo-octa-1,5-diene) with either hippuric acid [PhC(O)NHCH2COOH] or N-phenylanthranilic acid (ortho-PhNHC6H4COOH) in refluxing dichloromethane in the presence of silver(I) oxide gave the new organoplatinum derivatives [Pt{N(COPh)CH2COO}(cod)] and [Pt{N(Ph)C6H4COO}(cod)] respectively. Ligand substitution reactions of the cod ligand in [Pt{N(COPh)CH2COO}(cod)] provided a facile route to a selection of phosphine-substituted analogues [Pt{N(COPh)CH2COO}L2] [L = phosphatriazaadamantane (pta), PPh3, or L2 = Ph2PCH2CH2PPh2 or Fe(eta5-C5H4PPh2)2] via displacement of the labile cod ligand. The complexes were characterised using NMR spectroscopy, IR spectroscopy, and ESI mass spectrometry. The X-ray structure of [Pt{N(COPh)CH2COO}(cod)] is also reported.

To establish a structure?property relationship between polymer backbone structures and field-effect transistor performance has emerged as a new topic in organic electronics. The tunability and diversity of organic semiconductors provide the feasibility of controlling the electrical properties. Herein the characterization of thienothiophene-, dithiophenylethene-, biselenophene-, and diselenophenylethene-containing azaisoindigo copolymers is presented. As suggested by both theoretical calculations and experimental results, backbone electronic structure and linearity, density of side chains, aggregation, and thin film microstructure are involved in the differences in optical and electrical properties of these polymers. As the conjugation lengthens, n-type behaviors of the polymer semiconductors are suppressed, leading to a variation from nearly balanced ambipolar behaviors to predominant p-type characteristics. The effect of heteroatom substitution is also investigated. Notably, high hole and electron mobilities of 1.14 and 1.54 cm2 V?1 s?1 extracted from approximately ideal I?V curves are achieved with the top-gate/bottom-contact configuration transistors, demonstrating the potential of 7,7?-diazaisoindigo-based semiconducting polymers for applications in organic electronics.

Highly regio- and stereoselective borylstannylative carbocyclization of diynes 2a-f with the borylstannane 1 are efficiently catalyzed at room temperature by a series of palladium complexes such as Cl2Pd(PPh3)2, Cl2Pd[P(o-tolyl)3]2, Pd(PPh3)4, and Pd-(dba)2, giving 1-(borylmethylidene)-2-(stannylmethylidene)cycloalkane derivatives 3a-f in high yields. A 1,6-enyne (2g) also reacts similarly to afford a high yield of the corresponding cyclized product 3g.

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.HPLC of Formula: C34H28O2Pd, you can also check out more blogs about32005-36-0

The synthesis of a series of gem- and vic-diborylated vinylsilanes was accomplished via highly selective transition-metal-catalyzed syn-dimetalation to the alkynylmetal species. This protocol served as a general synthetic method toward regio- and stereodefined multisubstituted olefins. The key steps are the diastereoselective Suzuki-Miyaura cross-coupling reactions of gem- and vic-diborylated vinylsilanes, in which the two boron groups showed discrete reactivities to afford diverse precursors of multisubstituted olefins.
