The heterocycle-containing diarylmethane synthesis from chloromethyl(hetero)arenes with (hetero)arylboron reagents was attained using the palladium/ether-imidazolium chloride system. This coupling process tolerated a diverse range of heteroaromatic moieties with sufficient catalytic activity to achieve the efficient synthesis of various diheteroarylmethanes in good to excellent yields.

Silver carboxylate salts are widely used as additives in palladium-catalyzed C-H functionalization reactions. However, the role of these silver additives is often not fully understood. This paper describes an investigation of the role of AgOPiv in the stoichiometric activation of C6F5H at a well-defined PdII complex as well as in the PdII-catalyzed oxidative dimerization of 2-alkylthiophenes. Both in situ NMR spectroscopy and H/D exchange studies of the reactions of C6F5H implicate a role for AgOPiv in the C-H cleavage event, generating Ag-C6F5 as an intermediate. The catalytic studies show similar trends despite the different conditions and substrates, suggesting that AgOPiv promotes a similar metalation of the thiophene in the catalytic transformations. This proposal is supported by DFT calculations, which show energetically feasible pathways for concerted metalation-deprotonation of both 2-methylthiophene and pentafluorobenzene at [Ag(OPiv)]2. These studies suggest that initial metalation of C-H substrates at AgI carboxylates should be considered as a plausible pathway in C-H functionalization reactions involving mixtures of Ag and Pd salts.

An auto-tandem Pd-catalyzed process consisting of an intramolecular direct arylation and an intermolecular Buchwald-Hartwig reaction for C-ring amino-substituted 1-methyl-1H-alpha-carboline synthesis has been developed. A mechanistic study of the direct arylation reaction revealed a rate effect of the inorganic base on the C-H activation step (“base effect”). The amines, reagents in the tandem protocol, appear to have a similar effect on the direct arylation.

Reference of 1310584-14-5, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1310584-14-5, Name is Palladium-Xphos,introducing its new discovery.

The synthesis of a pentadentate ligand with strategically designed fluorinated arene groups in the second coordination sphere of a nonheme iron center is reported. The oxidatively resistant fluorine substituents allow for the trapping and characterization of an FeIV(O) complex at ?20 C. Upon warming of the FeIV(O) complex an unprecedented arene C-F hydroxylation reaction occurs. Computational studies support the finding that substrate orientation is a critical factor in the observed reactivity. This work not only gives rare direct evidence for the participation of an FeIV(O) species in arene hydroxylation but also provides the first example of a high-valent iron-oxo complex that mediates aromatic C-F hydroxylation.

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)].

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. category: catalyst-palladium. Introducing a new discovery about 14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II)

The reactivity of the metalloligand [Pt2(mu-S) 2(PPh3)4] towards a wide range of platinum(II) and palladium(II) chloride complex substrates [L2MCl2] has been explored, using the technique of electrospray ionisation mass spectrometry to directly analyse reaction solutions. In the majority of cases, products are formed by addition of the ML22+ fragment to the {Pt 2S2} core, giving trinuclear species [Pt 2(mu-S)2(PPh3)4ML 2]2+. The adducts with Pt(diene) [diene=cyclo-octa-1,5- diene (cod), norbornadiene], Pd(cod), Pd(bipy) (bipy=2,2?- bipyridine), Pt(PMe3)2 and Pt(PTA)2 (PTA=phosphatriaza-adamantane) moieties were synthesised and characterised on the macroscopic scale, with [Pt2(mu-S)2(PPh 3)4Pt(cod)] (BF4)2 and [Pt 2(mu-S)2(PPh3)4Pd(bipy)] (PF 6)2 also characterised by X-ray diffraction studies. No metal scrambling was found to occur, as has been observed in some previous cases involving the related complexes [Pt2(mu-Se)2(PPh 3)4] and [Pt2(mu-S)2(dppe) 2] (dppe=Ph2PCH2CH2PPh2). With cis-[PtCl2(SOMe2)2] the species [Pt 2(mu-S)2(PPh3)4PtCl(SOMe 2)]+ was formed, as a result of the lability of the SOMe2 ligand. With palladium(II)-phosphine systems, the observed product species is dependent on the phosphine; the bulky PPh3 ligand in [PdCl2(PPh3)2] leads primarily to the analogous known species [Pt2(mu-S)2(PPh 3)4PdCl(PPh3)]+, and a small amount of the metal-scrambled species [PtPd2S2(PPh 3)5Cl]+. In contrast, [PdCl2(PTA) 2], containing the small PTA ligand gave [Pt2(mu-S) 2(PPh3)4Pd(PTA)2]2+.

For the development of novel nanospace with unique electrostatic character, we prepared new capsular and tubular nanostructures by the quantitative assembly of metal ions and bent bisacridinium ligands. The capsule and tube have closed spherical and open cylindrical cavities, respectively, with diameters of around 1 nm surrounded by cationic polyaromatic panels. Thanks to the facile synthetic protocol (three steps), another polycationic capsule with an elliptical nanocavity was also prepared by using an elongated ligand. In spite of the absence of pendant hydrophilic groups, the spherical polyaromatic capsule shows sufficient water solubility due to the polycationic shell. Moreover, the highly cationic cavity (12+) can selectively encapsulate anionic organic compounds in water.

A novel palladium-catalyzed interannular selective C-H silylation of 1,1?-biaryl-2-acetamides is described. The combination of palladium catalyst with copper oxidant enables meta- or ortho-selective C-H silylation by employing hexamethyldisilane as a trimethylsilyl source, which relies on the control of NBE derivatives as a switch, thus providing straightforward access to divergent silicon-containing 1,1?-biaryl-2-acetamides.
