Dialkyl biarylphosphine ligands, presented in the context of Pd-catalyzed cross-coupling reactions, have been extensively applied in gold(I) catalysis giving rise to numerous transformations and reaction pathways otherwise inaccessible under the action of other gold(I) catalysts. This review emphasizes how this privileged ligand class, as well as recent modifications on the biarylphosphine motive, have triggered the discovery of new reactivities in our research program. Finally, the introduction of chiral information on the ligand scaffold provides new solutions to challenging gold(I)-catalyzed enantioselective transformations.

Reference of 84127-04-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 84127-04-8, Name is Bis(4-methoxyphenyl)phosphine. In a document type is Article, introducing its new discovery.

A series of functionalized diphosphine bisgold(i) complexes have been prepared from the corresponding diphosphine ligands Ar4P2 (Ar = MeC6H4, MeOC6H4, Me2NC6H4) and characterized by NMR spectroscopy and APCI mass spectrometry. Single-crystal X-ray diffraction analyses were performed to study the presence and importance of unsupported aurophilic interactions for the structure formation of these compounds. In general, the complexes featured monomeric structures with an antiperiplanar arrangement of the two AuCl units. The crystal packing greatly depended on the position of the substitution pattern (ortho vs. para). While for the ortho-substituted systems (OMe and NMe2) no ordered 3-dimensional networks were observed, the para-functionalized compounds formed regular layer structures. Here, aurophilic Au?Au interactions only played a minor role compared to intermolecular pi?pi interactions and hydrogen bonds.

In this review, the authors describe the role of gold in the chemistry of transition metal carbonyl clusters, a field that has been very active over the past fifty years. Both homo- and heteroleptic Au-containing species of metal carbonyl clusters, fully characterized by X-ray analysis, are discussed across three categories: those which are surface decorated by Au(I) fragments, cluster units connected by naked Au(I) atoms, and Au core?shell species with metallic gold structures embedded in the cluster frameworks.

The covalent immobilisation of palladium phosphine complexes on silica is demonstrated to be a viable method for the recovery of allylic alkylation catalysts. Both bidentate and monodentate phosphine ligands form stable palladium catalysts that could be recycled without catalyst deterioration and metal leaching. The regioselectivity of the immobilised catalyst for the alkylated products showed the same trend as the homogeneous analogues; in the alkylation of 3-methyl-but-2-enyl trifluoroacetate with sodium diethyl 2-methylmalonate we observed an increase in selectivity for the branched product from 11.6 to 58.3% on increasing the P-Pd-P bite angle from 93 to 108. The morphology of the silica support did not have impact on the catalyst performance as amorphous silica and MCM-41 supported Pd(1) gave a similar product distribution in the alkylation of 3-methyl-but-2-enyl trifluoroacetate with sodium diethyl 2-methylmalonate (42% linear (E) alkylated product and 58% branched alkylated product). We observed that a pre-modification of the silica surface using dichlorodimethylsilane was crucial for the recycling properties of the catalyst system. Using non-modified silica both the conversion (from 24 to 19%) and the regioselectivity (from 43 to 19% for the branched alkylation product) dropped in four consecutive catalyst runs using Pd(1)?. The modified systems yielded high conversions (68-64%) and increased regioselectivies for the branched alkylation product (58-57%) in four consecutive catalytic runs.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl, molecular formula is C20H27P.

Metal chalcogenides are technologically important materials. Physical, chemical, electrical and mechanical properties of these materials can be fine-tuned by manipulating their shape, size and composition. Although several methods are employed for their synthesis, single-source molecular precursor route has emerged as a versatile strategy for their synthesis and in controlling shape, size and composition of the material under moderate conditions. This chapter gives a brief coverage on the design and development of single-source molecular precursors which have been employed for the preparation of metal selenide/telluride nanocrystals and for deposition of thin films. The discussion includes synthesis of transition-, main group and f-block metal chalcogenolate and/or chalcogenide clusters as precursors and their conversion into metal chalcogenides in the form of thin films and nanostructures. Precursors for ternary metal chalcogenides are also included.

Materials such as trans-Fe(DMeOPrPE)2(X)(H2O)+ (DMeOPrPE = 1,2-[bis(dimethoxypropyl)phosphino]ethane; X = Cl or H) show considerable promise as sorbents for the removal of N2 from natural gas in a pressure swing process. One problem, however, is that in long-term tests these sorbents slowly degrade over a period of many weeks. This study probed the degradation mechanism for the purpose of finding ways to stabilize the sorbents. To investigate the likelihood of degradation initiated by Fe?P bond dissociation, the fluxional behavior of the related cis-Fe(DMeOPrPE)2(H)2 complex was investigated by variable temperature 1P{1H} NMR spectroscopy. Analysis of the spectra gave the following activation parameters for the fluxional process: DeltaH? = 11.6 kcal/mol and DeltaS? = ?9.2 cal/mol K. These results suggest that Fe?P bond dissociation (20?45 kcal/mol) is not occurring in the fluxional process and by implication that Fe?P bond dissociation is not initiating the decomposition of the trans-Fe(DMeOPrPE)2(X)(H2O)+ sorbents. Consequently, macrocycle ligands may not be the best approach for stabilizing the sorbents, as we have previously proposed. A ?tetrahedral jump? mechanism is proposed for the fluxional process in cis-Fe(DMeOPrPE)2(H)2.

In the course of our studies on non-peptide bradykinin (BK) B2 receptor ligands, it was suggested that the 4-substituent of the quinoline ring may play a critical role in determining binding affinities for human and guinea pig B2 receptors, as well as agonist/antagonist properties. We carried out an extensive investigation to elucidate the structure-activity relationships (SAR) for this key pharmacophore. Introduction of lower alkoxy groups to the 4-position of the quinoline ring of 3 led to the identification of 4-ethoxy derivative 22b as a unique partial agonist. This compound significantly stimulated inositol phosphates (IPs) formation in Chinese hamster ovary cells expressing the cloned human B2 receptor at concentrations greater than 10 nM and displayed one-tenth of the intrinsic activity of BK. The agonist activity of 22b was selective for the B2 receptor and was inhibited by selective peptide and non-peptide B2 antagonists. On the other hand, 22b strongly suppressed BK-induced IPs formation through the cloned human B2 receptor. Further studies on the key pharmacophore led to identification of a 2-picolyloxy moiety as a powerful agonist switch, leading to the discovery of a potent and efficacious non-peptide B2 agonist, 19a. Successive optimization of the acyl side chain afforded 38, which exhibited full agonist activity on stimulation of IPs formation. Furthermore, this strategy could be applied successfully to the benzimidazole series. The representative 1-(2-picolyl)benzimidazole derivative 47c increased PGE2 production at a 1 muM concentration to the same level as the maximum effect of BK. Thus, we have established the medicinal chemistry modifications required to convert our highly potent non-peptide B 2 antagonists to agonists with potent efficacy.
