PS-IIDQ: a supported coupling reagent for efficient and general amide bond formation

Polystyrene-IIDQ, a polymer-supported coupling reagent, was synthesized in three steps from Merrifield resin in 86% overall conversion. This reagent efficiently coupled carboxylic acids to amines in good yields and high purities, required no pre-activation step, and was tolerant of the order of reagent addition. PS-IIDQ was observed to be more efficient than polymer-supported carbodiimides (PS-EDC and PS-DCC) and gave higher yields than HATU for general amide bond formation, including the coupling of anilines and hindered substrates. When evaluated with five carboxylic acids and nine amines (including anilines and secondary amines) PS-IIDQ gave an average isolated yield of 73%.

A short and efficient synthesis of 3,4-dialkoxypyrroles

3,4-Dialkoxypyrroles are obtained in four steps from commercially available 2,5-dimethoxy-2,5-dihydrofuran (1). The dihydrofuran 1 is first oxidized by KMnO4 to the diol 2 which is bis-alkylated to 3a-d. Reaction of the in situ generated dialdehydes with a primary amine affords the N- substituted dialkoxypyrroles 4a-m. N-Benzyl-3,4-dialkoxypyrroles and N- allyl-dialkoxypyrroles are cleaved by sodium in liquid ammonia affording N- unsubstituted dialkoxypyrroles 5a-c in good overall yield.

This robust synthesis is suitable for the preparation of small pyridazine-based libraries.

New iridium complexes bearing C^N=N ligand for high efficiency OLEDs

Three iridium complexes, with 3-methyl-6-(2,4-difluoro-phenyl)pyridazine (mdfppya, C^N=N type ligand) as cyclometalated ligands, and picolinate (pic) or acetylacetonate (acac) as ancillary ligand, were synthesized and structurally characterized. Among these complexes,the homoleptic one, which contains two fluorine atoms on the cyclometalated phenyl moiety to lower the LUMO and a methyl group at the cyclometalated pyridazine part to raise the HOMO, possesses the shortest emission wavelength with peak of 506 nm. Importing ancillary ligands of picolinate (pic) and acetylacetonate (acac) yielded iridium complexes with emission of longer wavelength. The investigation of photophysical, electrochemical properties, as well as quantum chemistry calculation revealed optoelectrical property differences among them, corresponding principles were discussed. Photophysical, electrochemical features, quantum chemistry simulation and electroluminescence properties were systematically investigated. All complexes were applied to organic light-emitting diodes (OLEDs) as dopant emitters and the influence of ancillary ligands on device performance is significant. Based on pic-complex, maximum device efficiencies of 41.0 cd A?1, 33.9 lm W?1 and 11.62% were achieved. Additionally, this device exhibits extremely small efficiency roll-off. The reason for this good performance is mainly attributed to the high photoluminescence quantum yield and fast radiative decay rate of the phosphor, as wells rather matched energy levels in device.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
