Stable Palladium(0) and Palladium(II) Complexes Containing a New, Multifunctional and Semi-labile Phosphorus-Bisnitrogen Ligand

The new, multifunctional, semi-labile phosphorus-bisnitrogen ligand N-(2-diphenylphosphinobenzylidene)-2-(2-pyridyl)ethylamine, PNN, stabilises methyl(chloro)-, eta1-allyl(chloro)-, dichloro- and bis(tetrafluoroborate)palladium(II) PNN complexes in a terdentate coordination fashion, resulting in ionic palladium complexes, as well as an unprecedented palladium(0) PNN complex as is evidenced from 1H, 13C, 31P and 15N NMR spectra and an X-ray structural analysis of <(PNN)PdMe>+-.

Desymmetrization of an Octahedral Coordination Complex Inside a Self-Assembled Exoskeleton

The synthesis of a centrally functionalized, ribbon-shaped [6]polynorbornane ligand L that self-assembles with PdIIcations into a {Pd2L4} coordination cage is reported. The shape-persistent {Pd2L4} cage contains two axial cationic centers and an array of four equatorial H-bond donors pointing directly towards the center of the cavity. This precisely defined supramolecular environment is complementary to the geometry of classic octahedral complexes [M(XY)6] with six diatomic ligands. Very strong binding of [Pt(CN)6]2?to the cage was observed, with the structure of the host?guest complex {[Pt(CN)6]@Pd2L4} supported by NMR spectroscopy, MS, and X-ray data. The self-assembled shell imprints its geometry on the encapsulated guest, and desymmetrization of the octahedral platinum species by the influence of the D4h-symmetric second coordination sphere was evidenced by IR spectroscopy. [Fe(CN)6]3?and square-planar [Pt(CN)4]2?were strongly bound. Smaller octahedral anions such as [SiF6]2?, neutral carbonyl complexes ([M(CO)6]; M=Cr, Mo, W) and the linear [Ag(CN)2]?anion were only weakly bound, showing that both size and charge match are key factors for high-affinity binding.

Palladium Catalyzed C?O Coupling of Amino Alcohols for the Synthesis of Aryl Ethers

Amine containing aryl ethers are common pharmacophore motifs that continue to emerge from drug discovery efforts. As amino alcohols are readily available building blocks, practical methodologies for incorporating them into more complex structures are highly desirable. We report our efforts to explore the application of Pd-catalyzed C?O coupling methods to the arylation of 1,2- and 1,3-amino alcohols. We established general and reliable conditions, under which we explored the scope and limitations of the transformation. The insights gained have been valuable in employing this methodology within a fast-moving drug discovery environment, which we anticipate will be of general interest to the synthesis and catalysis communities.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 52409-22-0, help many people in the next few years.Recommanded Product: 52409-22-0

Suzuki-Miyaura Micellar One-Pot Synthesis of Symmetrical and Unsymmetrical 4,7-Diaryl-5,6-difluoro-2,1,3-benzothiadiazole Luminescent Derivatives in Water and under Air

The Suzuki-Miyaura cross-coupling reaction of 4,7-dibromo-5,6-difluoro-2,1,3-benzothiadiazole with different arylboronic acids can be efficiently carried out in water and under air by means of micellar coupling. The careful tuning of reaction conditions enables preparation of symmetrically and unsymmetrically substituted derivatives. The moderate to good yields obtained, along with the wide variety of available substitution patterns, makes this sustainable methodology very useful for the preparation of building blocks for luminescent optoelectronic materials.

Homoleptic palladium complexes with phosphine-amide or iminophosphine ligands

The reaction between Pd(dba)2 and phosphino-amide ligands yielded the unexpected Pd(II) homoleptic complexes [Pd(o-Ph2PC6H4CO-NR)2] [R = iPr (1), Ph (2), 4-MeC6H4 (3), 4-FC6H4 (4)], in which an kappa2-P,N coordination mode for diphenylphosphine-benzamidate ligands is observed. In order to induce amide protonation in the ligands and subsequent kappa2-P,O coordination, compounds (1-4) were treated with HClO4(aq) to give cationic complexes [Pd(o-Ph2PC6H4CO-NHR)2][ClO 4]2 (5-8). These complexes and the analogous with iminophosphine ligands [Pd(o-Ph2PC6H4CH{double bond, long}N-R)2] [ClO4]2 [R = iPr (9), Ph (10)] can be alternatively obtained when [PdCl2(PhCN)2] is treated with AgClO4 in the presence of the corresponding ligand. The reaction of Pd(dba)2 with iminophosphines has also been explored, yielding in this case the Pd(0) derivatives [Pd(o-Ph2PC6H4CH{double bond, long}N-R)2] [R = iPr (11), Ph (12)]. X-ray structures of (3), (4), (5), (8) and (9) have been established, allowing an interesting comparative structural discussion.

(Metallocenylphosphane)palladium dichlorides- synthesis, electrochemistry and their application in C-C coupling reactions

The synthesis and characterization of a series of metallocenylphosphanes of the type PR2Mc/Se=PR2Mc [Mc = Fc = Fe(eta5- C5H4)(eta5-C5H5), R = C6H5 (3a/4a), 2-MeC6H4 (3b/4b), c-C4H3O (3c/4c), tBu (3d/4d), c-C6H 11 (3e/4e); Mc = Rc = Ru(eta5-C5H 4)(eta5-C5H5), R = C 6H5 (6a/7a), 2-MeC6H4 (6b/7b), c-C4H3O (6c/7c), c-C6H11 (6d/7d)] and their palladium complexes [PdCl2(PR2Mc)2] [Mc = Fc, R = C6H5 (9a), 2-MeC6H4 (9b), c-C4H3O (9c), tBu (9d), c-C6H 11 (9e); Mc = Rc, R = C6H5 (10a), 2-MeC 6H4 (10b), c-C4H3O (10c), c-C 6H11 (10d)] is reported. The solid-state structure of 4b confirms the tetrahedrally distorted geometry at phosphorus with the o-tolyl groups indicating steric congestion, which is confirmed by 1H and 13C{1H} NMR spectroscopy. Phosphanes 3, 4, and 9 were characterized by cyclic voltammetry with [N(nBu)4][B(C 6F5)4] as the supporting electrolyte. In general, the first oxidation occurs at the phosphane metallocenyl unit(s), although the appropriate Pd complexes are oxidized at more positive potentials. Depending on the phosphane or selenophosphane, follow-up reactions occur, which are discussed. In contrast, the palladium complexes show reversible redox behavior. UV/Vis/NIR spectroelectrochemical studies carried out on 9b indicate an electrostatic interaction between the two terminal ferrocenyl groups. All of the palladium complexes were examined as catalysts in Heck and Suzuki C-C cross-coupling and showed high catalytic activities. These results can be correlated to the electronic (1J31P77Se) parameters of the selenophosphanes.

Palladium-catalyzed silaborative carbocyclizations of 1,6-diynes

An addition/cyclization reaction of 1,6-diynes was developed for the synthesis of highly substituted 1,2-dialkylidenecycloalkanes. In this work, 1,6-diynes reacted with (dimethylphenylsilyl)pinacol-borane in the presence of a palladium catalyst to afford 1,2-dialkylidenecycloalkanes bearing silyl and boryl groups with a (Z,Z)-configuration in good to excellent yields. Moreover, the corresponding products could be easily converted into other synthetically useful compounds. This protocol provides an efficient and practical method of heteroelement-element linkage addition to the unsaturated 1,6-diynes.
