New indolo[1,2-c]quinazolines for single-crystal field-effect transistor: A united experimental and theoretical studies

Here, we account the synthesis and characterization of a series of symmetrical fused heterocyclic aromatic hydrocarbons (HAHs) with an indolo[1,2-c]quinazoline (IQ) as the core moiety. All the new HAHs IQ series were systematically investigated by using various spectroscopic methods. Furthermore, their photo-physical properties were supported by density functional theory (DFT) and time-dependent density functional theory (TDDFT) studies to support the experimental findings. The tetramethyl-substituted indolo[1,2-c]quinazoline (TMIQ) compound is shown to exhibit the shifted type of π–π stacking interactions, which render this series as a new semiconducting material. Single-crystal-based field-effect transistor devices of TMIQ exhibited efficient charge transport behavior, giving a p-channel field-effect mobility of 0.25 cm2?V?1?s?1 with an on/off ratio of 5 × 105.

Flexible and practical synthesis of 3-oxyindoles through gold-catalyzed intermolecular oxidation of o-ethynylanilines

A novel gold-catalyzed intermolecular oxidation of o-ethynylanilines has been developed. A range of functionalized 3-oxyindoles are readily accessed by utilizing this strategy. Importantly, this gold-catalyzed oxidative process outcompetes the typical ind

NHC-stabilized gold(I) complexes: Suitable catalysts for 6-exo-dig heterocyclization of 1-(o-Ethynylaryl)ureas

Figure presented 3-substituted 1-(o-ethynylaryl)ureas 1 selectively undergo either 6-exo-dig or 5-endo-dig cyclization (to give 4-methylene-3,4-quinazolin- 2-ones 2 or indoles 3, respectively) depending on the choice of the metal, ligand, and reaction conditions. The best results (up to 96% yield) in the preparation of the hydroamination products 2 are achieved with the highly bulky NHC-stabilized cationic gold(I) complex [Au(IPr)]+. Conversely, ureas bearing an internal alkyne lead to the 5-endo-dig cyclization mode regardless of the gold(I) complex employed. Whereas the nature of the substituent at N-3 does not have any influence on the regiochemistry observed, it does, in some cases, affect the efficiency of these transformations.
