“…As seen on cyclic voltammogram in Figure . The first well‐defined anodic peak, situated at potential of 0.2 V, SCE indicates one electron oxidation of 2‐aminopyridine , and second anodic peak, occurred at potential of ∼0.5 V, SCE denotes second electron oxidation from sp2 nitrogen of 2‐aminopyridene (Scheme ) the scan rate was 0.01 Vs −1 reference electrode corresponds to the oxidative double hydroamination of DMAD yielding imidazopyridine. It was thus proven from careful investigation of graph that there are two electron oxidations in the overall process (Scheme ).…”

A novel facile and diastereoselective synthesis of imidazopyridine with high atom economy in water as a green solvent under synergic effect of microwave activation and phase transfer catalysis from readily available 2‐aminopyridine and electrophilic alkyne, dimethyl acetylene dicarboxylate has been developed. The strategy of the protocol involves heterocyclisation via double hydroamination of dimethyl acetylene dicarboxylate in biphasic system catalyzed by benzyltriethylammonium bromide activated by microwave irradiation. The transformation proceeded smoothly and quantitatively at an ambient temperature. The reaction sequence of the protocol was also proved by electrochemical synthesis of imidazopyridine using same starting materials under similar reaction conditions.

“…Therefore, PAB monomer was dissolved in 0.1 mol dm À3 LiClO 4 /ACN for the electropolymerization process (Table 1). In the literature, Saraswat et al 34 have studied the electropolymerization of aniline on Pt electrode in LiClO 4 /ACN solution.…”

In this study, aniline-based monomer, N, N′-(propane-1,3-diyl)bis(2-aminobenzamide), (PAB), was synthesized and characterized by proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), and Fourier transform infrared spectroscopy. The electropolymerization of the monomer was performed on glassy carbon electrode by cyclic voltammetry (CV). The effects of solvent, dopant, scan number, and scan rate on the electropolymerization and properties of the poly(PAB) films were investigated. The modified electrode was also characterized by Fourier transform infrared-attenuated total reflection spectroscopy and scanning electron microscopy–energy-dispersive X-ray analysis. The capacitive properties of the poly(PAB) films were firstly tested by electrochemical impedance spectroscopy. The highest specific capacitances ( Csp) of poly(PAB) films were obtained as Csp = 6.22 mF cm−2 in 0.1 M lithium perchlorate/acetonitrile (ACN) for [PAB]0 = 20 mmol dm−3 and Csp = 16.9 mF cm−2 in 1 mol dm−3 sulfuric acid for [PAB]0 = 5 mmol dm−3 at the scan rate of 5 mV s−1 from CV measurements. This study is novel because it was the first study on capacitance performances of poly(PAB) films in the literature.

“…CP-based heterocycles such as polyaniline (PANI) or polythiophene (PTH) have been extensively studied because they exhibit interesting electrochemical properties [7,[10][11][12][13][14], including ease of doping or, in the case of PANI, excellent redox resistance [15,16]. Likewise, among the CPs, PTH has been considered a model concerning charge transfer as it possesses good stability under ambient conditions in its doped and undoped state [17].…”

Synthesis and characterization of aniline and thiophene and/or alkylthiophenes polymers

Three new polymers, obtained by reacting thiophene or 3-alkylthiophenes as electron donors with aniline as acceptor in a donor-acceptor structure, were synthesized via oxidative polymerization using iron(III) chloride (FeCl 3 ). The final products were characterized utilizing conventional techniques such as IR, NMR, UV-Vis spectrometry, which enabled demonstrating that an increase of the aliphatic chain length causes significant solubility increase of the system, without modifying the conductivity. On the other hand, observed an important variation of the thermal stability of the polymer when medium-length aliphatic chains were inserted was observed; in contrast, the addition of a methyl group (short chain length) hardly affected the mentioned properties.
