Diaza-analogs of benzopyrene and perylene containing thienyl and 4-(phenylamino)phenyl groups: Synthesis, characterization, optical and electrochemical properties

Series of 1,8-diazabenzopyrenes and 1,7-diazaperylenes with thienyl or 4-(phenylamino)phenyl groups were designed and synthesized by a one-pot process from the functionalized terminal alkynes and either 1,4- or 1,5-diiodoanthraquinones in order to investigate the effect of extending π-conjugation at the 2,7- and 2,8-positions on the optical and electrochemical properties. The substances synthesized were characterized by X-ray analysis, cyclic voltammetry, UV–vis and luminescence spectroscopy. Energies and spin-densities of frontier molecular orbitals were calculated by DFT. Practically planar crystal structures of 1,8-diazabenzopyrene and 1,7-diazaperylene with thienyl groups were confirmed by X-ray diffraction data. Solid-state luminescence was obtained for the synthesized substances in drop-casted films and in 1,4-dioxane/water mixtures.

N-heterocyclic carbene-palladium(II)-4,5-dihydrooxazole complexes: Synthesis and catalytic activity toward amination of aryl chlorides

A series of novel N-heterocyclic carbene-palladium(II)-4,5-dihydrooxazole (NHC-PdII-Ox) complexes 3 were successfully synthesized from commercially available imidazolium salts 1, PdCl2, and 4,5-dihydrooxazoles 2 in a one-step process, and these complexes showed efficient catalytic activity toward the amination of aryl chlorides. Both secondary and primary amines were tolerated under the same reaction conditions. Under the optimal reaction conditions, the expected coupling products were obtained in moderate to high yields.

Well-defined NHC-Pd(II)-Im (NHC=N-heterocyclic carbene; Im=1-methylimidazole) complex catalyzed C-N coupling of primary amines with aryl chlorides

We report herein a well-defined NHC-Pd(II)-Im (NHC=N-heterocyclic carbene; Im=1-methylimidazole) complex catalyzed C-N coupling of primary amines with aryl chlorides. Under the optimal reaction conditions, a variety of primary amines can be coupled with aryl chlorides to give the amination products in good to high yields within 4 h. It is worthy of noting here that the NHC-Pd(II)-Im complex showed especially high catalytic activity toward challenging sterically hindered substrates including both of aryl amines and aryl chlorides. In addition, alkyl amines were also proved to be suitable reaction partners to give the corresponding amination products in good to high yields.
