Bis-doenes 4 react with distannanes 1, disilanes 2, and silylstannanes 3 in the presence of a catalytic amount of a palladium complex to afford carbocyclization-distannylation, -disilylation and -silastannylation products in high yields.Reaction of distannanes 1a, b with bis-dienes 4a, b as well as reaction of disilane 2b with bis-diene 4d proceeded regio- and stereo-selectively to afford a single product: trans-(E),(Z) isomers.Regio and stereo-selective reaction was also realized with the disilane 2b and bis-diene 4e to provide only trans-(E),(E) isomer.In other cases, the reactions proceeded regioselectively, but the stereoselectivity was modest.The X-ray crystal structures of the cyclopropanes 10 and 11 have been determined.

A xanthene-based bismuthane/phosphane chelating ligand has been accessed that has enabled the synthesis of a palladium(0) bismuthane complex. The bismuthane donor proved to be hemilabile as it switched to a dangling position upon addition of O2 that gave a palladium(II) peroxide complex. Unlike the corresponding 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) palladium peroxide, the bismuth analogue could be employed for catalytic phosphane oxidation and oxidative phenol coupling.

Intermetallic compounds are atomically ordered inorganic materials containing two or more transition metals and main-group elements in unique crystal structures. Intermetallics based on group 10 and group 14 metals have shown enhanced activity, selectivity, and durability in comparison to simple metals and alloys in many catalytic reactions. While high-temperature solid-state methods to prepare intermetallic compounds exist, softer synthetic methods can provide key advantages, such as enabling the preparation of metastable phases or of smaller particles with increased surface areas for catalysis. Here, we study a generalized family of heterobimetallic precursors to binary intermetallics, each containing a group 10 metal and a group 14 tetrel bonded together and supported by pincer-like pyridine-2-thiolate ligands. Upon thermal decomposition, these heterobimetallic complexes form 10-14 binary intermetallic nanocrystals. Experiments and density functional theory (DFT) computations help in better understanding the reactivity of these precursors toward the synthesis of specific intermetallic binary phases. Using Pd2Sn as an example, we demonstrate that nanoparticles made in this way can act as uniquely selective catalysts for the reduction of nitroarenes to azoxyarenes, which highlights the utility of the intermetallics made by our method. Employing heterobimetallic pincer complexes as precursors toward binary nanocrystals and other metal-rich intermetallics provides opportunities to explore the fundamental chemistry and applications of these materials.

The five non-doped red devices showed emission at 680, 676, 680, 692 and 656 nm with efficiencies of 2.93, 1.33, 2.58, 2.96 and 1.04 cd/A. The three non-doped green and three blue devices emitted EL peaks at 516, 532, 420, 424, 457 and 520 nm with maximum efficiencies of 0.33, 0.55, 0.45, 1.25, 0.43, and 0.45 cd/A, respectively. The three blue devices exhibited narrower full width at half maximum of 42, 49 and 84 nm. EFPAFN, EFPAEF, PhMPAFN and PhMPAEF were multifunctional compounds as emitters and hole-transporting materials, device efficiencies kept relatively small decline within a wide range of current density. Fumaronitrile or fluorene bridge with the same non-planar fluorenyl or phenanthryl amino unit and the different device fabrications achieved non-doped red-green-blue (R-G-B) EL emissions.

Arenediazonium tetrafluoroborates (ArN2BF4 where Ar = Ph, 4-MeC6H4, 4-BrC6H4, 4-IC6H4 and 4-NO2C6H4) reacted easily with CH2=CHSiMe3 at 25 deg C to give ArCH=CH2, (E)-ArCH=CHSiMe3 and Ar(Me3Si)C=CH2 in excellent yields under palladium(0) catalysis. (E)-ArCH=CHSiMe3 compounds were obtained predominantly and isolated in good yields by using an excess of CH2=CHSiMe3 over ArN2BF4.Protodesilylation of the reaction mixture afforded styrene derivatives.

A straightforward route toward construction of alpha-quaternary chiral beta-lactam moiety via Rh(II)/Pd(0)-catalyzed stereoselective relay catalytic reaction is reported. This asymmetric dual relay catalysis involves Rh(II)-catalyzed enantioselective intramoluecular C-H insertions of alpha-diazoamides, and sequential Pd(0)-catalyzed diastereoselective intermolecular allylic alkylation. Under mild reaction conditions, a broad range of alpha-quaternary allylated chiral beta-lactams have been synthesized in high yields (up to 99%) with excellent stereoselectivities [up to diastereomeric ratio (dr) >99:1, up to 98% enantiomeric excess (ee)].

The asymmetric allylic alkylation (AAA), which features employing active allylic substrates, has historical significance in organic synthesis. The allylic C-H alkylation is principally more atom- and step-economic than the classical allylic functionalizations and thus can be considered a transformative variant. However, asymmetric allylic C-H alkylation reactions are still scarce and yet underdeveloped. Herein, we have found that Z/E- and regioselectivities in the Pd-catalyzed asymmetric allylic C-H alkylation of 1,4-dienes are highly dependent on the type of nucleophiles. A highly stereoselective allylic C-H alkylation of 1,4-dienes with azlactones has been established by palladium-chiral phosphoramidite catalysis. The protocol proceeds under mild conditions and can accommodate a wide scope of substrates, delivering structurally divergent alpha,alpha-disubstituted alpha-amino acid surrogates in high yields and excellent levels of diastereo-, Z/E-, regio-, and enantioselectivities. Notably, this method provides key chiral intermediates for an efficient synthesis of lepadiformine marine alkaloids. Experimental and computational studies on the reaction mechanism suggest a novel concerted proton and two-electron transfer process for the allylic C-H cleavage and reveal that the Z/E- and regioselectivities are governed by the geometry and coordination pattern of nucleophiles.
