A simple and efficient approach to the synthesis of fluorinated amino-substituted acetophenones in good to excellent yields is reported. The heart of the proposed method consists of conversion of a Me 3 Si-C≡C- moiety into a MeC(=O)- group in the presence of p -tolu ene sulfonic acid (p -TSA) passing a stage of ethynylaniline formation. The reaction is metal-free, proceeds under mild conditions, and uses readily available starting compounds (trimethylsilylarylacetylene derivatives). The reaction provides access to amino-substituted acetophenones, which may serve as precursors for the synthesis of polyfluorinated azaheterocycles, having potential anticarcinogenic activity.

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.
