Reactions of m-chloroperoxybenzoic acid with dimeric cyclopalladated complexes derived from 2-phenyl-2-oxazolines

Cyclopalladated complexes (CPCs) (S,S)-di-mu-Cl(kappa2-C,N)2Pd2 (1a,b) and (S,S)-di-mu-OAc(kappa2-C,N)2Pd2 (7a,b) obtained from (S)-4-t-butyl-(a) and (S)-4-ethyl-2-phenyl-2-oxazoline (b) were reacted with m-chloroperoxybenzoic acid (m-CPBA) at room temperature in methylene chloride, ethyl acetate or acetonitrile followed by workup with lithium chloride. Oxidation products formed in these reactions include dinuclear complexes (S,S)-di-mu-Cl(kappa2-N,O)2Pd2 (2a), (S,S)-di-mu-oxo(kappa2-N,O)2Pd2Cl2 (2b), and (S,S)-di-mu-(m-Cl-C6H4CO2)(kappa2-N,O)2Pd2 (3a,b), mononuclear derivatives (S,S)-bis(kappa2-N,O)Pd (4a,b) and dinuclear monooxidation complexes (S,S)-di-mu-Cl(kappa2-N,O)(kappa2-C,N)Pd2 (5a,b). Each complex was isolated in low yield (6-46 %) with the combined yield of oxidation products reaching up to 64 %. The best selectivity in product distribution was observed for the reactions of mu-OAc-CPCs 7a,b with 2.7 equiv. of m-CPBA in acetonitrile, in which oxygen-insertion adducts 2a and 4b were isolated in 44 and 46 % yields, respectively.

Palladium-Catalyzed Direct Approach to alpha-Trifluoromethyl Alcohols by Selective Hydroxylfluorination of gem-Difluoroalkenes

A novel palladium-catalyzed selective hydroxylfluorination of gem-difluoroalkenes has been developed. By employing easily obtainable gem-difluoroalkenes and NFSI as the fluorine source, the scope, advantages, and limitations of this reaction were investigated. The reaction presents an efficient synthesis to afford a series of alpha-trifluoromethyl alcohols in good to excellent yields. Furthermore, this reaction probably proceeds via oxidation of Pd0 to PdII fluoride complex by NFSI, followed by fluoropalladation of gem-difluoroalkenes to generate an alpha-trifluoromethylbenzyl?Pd intermediate. And this strategy offers more possibilities for the construction of other bonds, such as C?C, C?N and C?S.

Unsaturated cyclopentadienyl-molybdenum and tungsten carbonyl cluster complexes containing Pd- And Pt(PBu3t) groups

A series of new bimetallic cluster compounds, Cp2M 2(CO)4[M?(PBu3t)]2 [M = Mo, M? = Pt (9); M = Mo, M? = Pd (10); M = W, M? = Pt (11); M = W, M? = Pd (12)], have been synthesized from reactions of [CpM(CO)3]2 (M = Mo, W) with an excess of M?(PBu3t)2 (M? = Pt, Pd) at various temperatures. Each compound was fully characterized by IR, 1H and 31P NMR, and single-crystal X-ray diffraction analyses. The metal atoms in the structure of 9 are arranged in a butterfly configuration, while the metal atoms of 10-12 adopt a tetrahedral geometry. Compounds 9 and 12 contain two edge-bridging and two triply bridging carbonyl ligands, 10 contains four triply bridging carbonyl ligands, and 11 contains two terminal and two edge-bridging carbonyl ligands. Each of the products is electron-deficient and the M-M bonds, M = Mo and W, are short, Mo-Mo = 2.6535(4) A in 9 and 2.6362(4) A in 10, W-W = 2.6168(9) A in 11 and 2.6320(7) A in 12, which is indicative of some localized multibond character between these metal atoms within the cluster framework. The nature of the bonding within the clusters was explored with DFT calculations (ADF 2004.01, PW91) for the title compounds in C2 symmetry as well as for a hypothetical, two-electron-reduced [Cp2Mo2Pd2(CO) 4(PBu3t)2]2- species.

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 53199-31-8, help many people in the next few years.Safety of Bis(tri-tert-butylphosphine)palladium

Suzuki-miyaura cross-coupling of unprotected, nitrogen-rich heterocycles: Substrate scope and mechanistic investigation

The Suzuki-Miyaura cross-coupling of unprotected, nitrogen-rich heterocycles using precatalysts P1 or P2 is reported. The procedure allows for the reaction of variously substituted indazole, benzimidazole, pyrazole, indole, oxindole, and azaindole halides under mild conditions in good to excellent yields. Additionally, the mechanism behind the inhibitory effect of unprotected azoles on Pd-catalyzed cross-coupling reactions is described based on evidence gained through experimental, crystallographic, and theoretical investigations.

In an alternative aspect, step b] of the above defined method is replaced by the step of determining the presence of a mutated CTNNB1 protein in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 protein indicates that the tumor is susceptible to treatment with a TTK inhibitor. In a further alternative, step b] comprises determining an altered expression of a CTNNB1 regulated gene, whereby an altered expression of a CTNNB1 regulated gene indicates that the tumor is susceptible to treatment with a TTK inhibitor.

Novel Di- and Trinuclear Palladium Complexes Supported by N,N?-Diphosphanyl NHC Ligands and N,N?-Diphosphanylimidazolium Palladium, Gold, and Mixed-Metal Copper-Gold Complexes

The reaction of the trinuclear complex [Ag3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Ag3; PCNHCP = N,N?-bis(di-tert-butylphosphanyl)imidazol-2-ylidene) with [Pd(dba)2] afforded the trinuclear palladium complex [Pd3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd3) and the dinuclear palladium(I) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd2). The assignment of the oxidation state of the metals in the mixed-valence Pd3 chain as Pd0-PdII-Pd0 was based on the reactivity of the complex with 2,6-dimethylphenyl isocyanide and density functional theory calculations. Reaction of PCNHCP with [PdMe2(tmeda)] afforded the palladium(II) complex [PdMe2(PCNHCP,kappaP,kappaCNHC)] (Pd-Me2), with PCNHCP acting as a bidentate ligand. The reaction of PCNHCP with [Pd(dba)2] led to a dinuclear palladium(0) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)](dba) (Pd2-dba); attempted replacement of the remaining dba by PCNHCP failed. The imidazolium triflate PCHP, precursor to PCNHCP, was reacted with [Pd2(dba)3]¡¤CHCl3 to give the (2 + 2) metalla-mesocyclic cationic palladium(0) complex [Pd2(mu2-PCHP,kappaP,kappaP)2] (PCHP-Pd2), which resisted further deprotonation of the imidazolium cation. In contrast, PCHP reacted with [AuCl(tht)] to give [Au2Cl2(mu2-PCHP,kappaP,kappaP)] (PCHP-Au2), in which one Au-Cl moiety is bound to each P donor. Further reaction of PCHP-Au2 with [Au{N(SiMe3)2}(PPh3)] afforded a mixture of the trinuclear [Au3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Au3) and [AuCl(PPh3)], while reaction with [CuMes]5, where Mes = 2,4,6-trimethylphenyl, resulted in a novel, centrosymmetric, heterometallic complex [Au2Mes2(Cu4Cl4)(PCHP,kappaP,kappaP)2] (PCHP-AuCu) featuring a new PCHP-AuMes metalloligand bridging a Cu¡¤¡¤¡¤Cu diagonal of a Cu4Cl4 cubane via the P and AuMes functionalities.
