A sydnone cycloaddition route to pyrazole boronic esters

(Chemical Equation Presented) From dipole to diazole! A direct and regioselective route to functionalized pyrazole boronic esters is developed that employs the cycloaddition of alkynylboronates with sydnones. Functionalization of these products by Suzuki coupling and N-deprotection processes highlight the potential synthetic utility of these species.

Palladium-Catalyzed Cross-Coupling Reaction of Alkyltrifluorosilanes with Aryl Halides

A cross-coupling reaction of alkyltrifluorosilanes with aryl halides was achieved using a catalytic amount of tetrakis-(triphenylphosphine)palladium(0) and excess of tetrabutylammonium fluoride (TBAF) at 100C with high chemoselectitvity. Functional groups like nitro, ketone carbonyl, and formyl tolerated the coupling conditions. Because potassium(18-crown-6) alkyltetrafluorosilicates also underwent a cross-coupling reaction in the presence of an additional molar amount of TBAF, the active species of the coupling reaction was assumed to be pentacoordinate silicates. TBAF in excess was considered to be required for trapping the tetrafluorosilane produced in the catalytic cycle of the cross-coupling reaction.

Soluble polymer-supported convergent parallel library synthesis.

Soluble polymer-supported convergent synthesis has for the first time been successfully exploited for parallel library synthesis; sub-libraries of tripeptide iodoarenes and arylboronic acids reacted smoothly in a multipolymer PdII-catalyzed Suzuki coupling reaction to generate a library of bisaryl-linked hexapeptides.

Bis-ZnII salphen complexes bearing pyridyl functionalized ligands for efficient organic light-emitting diodes (OLEDs)

Inspired by the emissive features of ZnII complexes based on bis-Schiff base ligands, bis-ZnII salphen complexes bearing pyridyl functionalized ligands have been successfully synthesized. Their photophysical features, electrochemical behavior and electroluminescent (EL) properties have been investigated in detail. The functionalized bis-ZnII salphen complexes can exhibit high thermal stability up to 417 C, and their photoluminescence (PL) spectra show a maximal emission wavelength peak at ca. 565 nm both in solution and PMMA doped films. The PL investigation of the neat films for these functionalized bis-ZnII salphen complexes indicated that the pyridyl functionalized ligands can effectively reduce the degree of molecular aggregation to enhance their emission intensity. Taking advantage of the charge carrier injection/transporting ability of the pyridyl functionalized ligands and their dendritic design, the optimized EL devices fabricated by a simple solution-processing method can achieve a peak luminance (Lmax) of 3589 cd m-2, a maximal external quantum efficiency (etaext) of 1.46%, a maximal current efficiency (etaL) of 4.1 cd A-1 and a maximal power efficiency (etap) of 3.8 lm W-1. These results should afford important instructions for exploiting high performance fluorescent emitters based on dinuclear ZnII complexes.

The synthesis of a new class of 1,4-bis(diphenylphosphino)-1,3-butadiene was discussed. Catalyst mixtures based on 1,2,3,4-Ph4-NUPHOS were found to be superior to those based on BINAP, with activities of 6900 and 260 (mol of product) (mol of palladium)-1h-1 respectively. The applications in palladium catalyzed cross-coupling reactions were also discussed.

Bimetallic DppfM(II) (M = Pt and Pd) dithiocarbamate complexes: Synthesis, characterization, and anticancer activity

A series of bimetallic dppfM(II) (dppf = 1,1?-bis (diphenyphosphino) ferrocene; M = Pt and Pd) dithiocarbamate complexes is synthesized and characterized by spectroscopic methods and single-crystal X-ray diffraction. Their antitumor activities in vitro are investigated by MTT assays against four cancer cell lines. The anticancer studies indicate most of the complexes display good to excellent antitumor activity. Remarkably, the platinum complex with a pyrrolidinyl substituent (3b) was identified as the most promising candidate due to its high potency and broad spectrum of activity.

Palladium-catalyzed incorporation of atmospheric CO2: Efficient synthesis of functionalized oxazolidinones

Methods to incorporate atmospheric CO2 into organic molecules are on demand. Here we present two Pd-catalyzed multicomponent reactions that provide functionalized oxazolidinones from propargylamines, aryl halides and CO2 as starting materials. These transformations, devoid of high CO2 pressures, represent a streamlined stereocontrolled synthesis of previously inaccessible versions of these useful heterocycles in an atom-economic manner, as up to four new single bonds are formed in a single synthetic operation.

Topological Effects on Intramolecular Electron Transfer via Quantum Interference

The three isomers of diferrocenylbenzenes (ortho, 1o; meta, 1m; para, 1p) as well as 5-substituted derivatives of m-diferrocenylbenzene with R = NH2 (2), Cl (3), CH3 (4), CN (5), NO2 (6), and N(CH3)33+ (7) have been prepared. Crystal structures of 1o, 3, and 5 have been solved. In 3 and 5, the cyclopentadienyl rings are nearly parallel to the benzene mean planes with angles ranging from 9.99(5) to 14.74(5). One ferrocene group is above and the other below the mean molecular plane. For 1o, there is an important twist between the benzene and cyclopentadiene rings (68.6(8) and 32.5(8)) for steric reasons. Controlled potential electrolysis yields the mixed-valence ferrocene/ ferrocenium species in comproportionation equilibrium with homovalent species. Intervalence transitions have been observed and corrected from comproportionation. From the intervalence band parameters, metal-metal couplings (Vab) are calculated using Hush’s equation. The values are much higher for 1o (0.025 eV) and 1p (0.043 eV) than for 1m (0.012 eV) and exhibit little or no variation for the substituted m-diferrocenylbenzenes 2-6. These results are rationalized by extended Hueckel molecular orbital calculations. The weakness of the interaction in 1m can be ultimately traced to a quantum Interference effect, i.e., a cancellation of the contributions of two electron transfer paths. This cancellation occurs because each path implies a mixing of metal orbitals with a different ligand orbital, and the resulting molecular orbitals exhibit different symmetries.
