In this study, Poly(2-ethylhexyl acrylate) (PEHA) thin films were deposited on different substrates by initiated chemical vapor deposition (iCVD) technique. Being a long alkyl chain acrylate with a suitably low glass transition temperature, PEHA is an important member of acrylates family, which ...

The aminocarbonylation of phenylacetylene has been studied in the presence of the catalytic system formed by palladium acetate in combination with (2-pyridyl)diphenylphosphine and methanesulfonic acid. The catalytic activity is strongly influenced by the nature of the amine: good reaction rates ...

Anilines as archetypes for aromatic amines, which play an important role in the production of, e.g., dyestuffs, plastics, pesticides or pharmaceuticals were investigated in their reaction with ozone. Due to their high reactivity towards ozone (1.2 × 105–2.4 × 106 M−1 s−1) the investigated ani...

Aniline oligomers prepared via the oxidation of aniline under alkaline conditions at various concentrations of ammonia were carbonized at 650 °C in inert atmosphere. Subsequently, the prepared particles were mixed with silicone oil and the suspensions were used as electrorheological fluids. Aft...

Aniline was oxidized with silver nitrate in aqueous solutions of sulfonic acids: camphorsulfonic, methanesulfonic, sulfamic, or toluenesulfonic acids. Polyaniline–silver composites were produced slowly in 4 weeks in good yield, except for the reaction, which took place in sulfamic acid solution...

The reaction between aniline and p-benzoquinone in an aqueous solution of methanesulfonic acid (MSA) yields 2,5-dianilino-p-benzoquinone. It forms salts with MSA, which are conducting, the maximum conductivity being 2.6 × 10−4 S cm−1 when the preparation was carried out in 5 M MSA. After deprot...

New aniline derivative, containing substituted chalcone moiety was synthesized by starting from 3-amino acetophenone and 4-pyrridine carboxyaldehyde in the presence of NaOH. The obtained chalcone containing aniline was polymerized oxidatively in water in the presence of dopant such as methanesul...

The aniline-based oligomers were synthesized by oxidation of aniline with p-benzoquinone in the solutions of methanesulfonic acid, 2,5-dianilino-p-benzoquinone methanesulfonate salt being the main product. The synthesized samples were characterized by UV–visible and FTIR spectroscopies and comp...

Aniline was oxidized with three strong inorganic oxidants (ammonium peroxydisulfate, cerium(IV) sulfate, potassium dichromate), two weak inorganic oxidants (iron(III) chloride, silver nitrate), and one organic oxidant (p-benzoquinone) in aqueous solutions of methanesulfonic acid (MSA) of various...

Polyaniline (PANI)/graphene composites were prepared by the in-situ polymerization of aniline in a 1 M aqueous solution of methanesulfonic acid (MSA) containing graphene, which was prepared separately from graphite powders by simple sonication in MSA. Graphite powders spontaneously exfoliated to...

Zinc 2, (3)-tri-(phenylthio)-2, (3)-carboxy phthalocyanine (ZnPc(COOH)(SPh)3), zinc 2, (3)-tetra-(phenylthio) phthalocyanine (ZnPc(SPh)4) and 2, (3)-tetra-(phenylthio) phthalocyanine (H2Pc(SPh)4) were synthesized and their photophysical behavior were compared with those of a number of zinc phtha...

A fluoride-induced nucleophilic (phenylthio)difluoromethylation method using TMS–CF2SPh has been achieved. This new methodology efficiently transfers “PhSCF2” group into both enolizable and non-enolizable aldehydes and ketones to give corresponding (phenylthio)difluoromethylated alcohols in g...

Crystal structures of (phenykthio)acetic acid (PTAH) (1), and the zinc(II) and cadmium(II) complexes of the PTAH have been determined by X-ray diffraction. The acid, PTAH, is monoclinic, space group P22/n, with Z = 4 in a cell of dimension a = 7.666(1), b = 5.638(1), c = 18.939(2) Å, β = 99.33(...

Crystal structures of four univalent metal complexes with (phenylthio)acetic acid (PTAH), (2,4-dichloro-5-methylphenylthio)acetic acid (DCMPTAH), and 2-(phenylthio) propionic acid (PTPAH) have been determined using X-ray diffraction. The thallium complex, [Tl(PTA)(PTAH)]n, (1) is orthorhombic, s...

Chagas disease is an illness caused by the protozoan parasite Trypanosoma cruzi. The current chemotherapy is based on benznidazole, and, in some countries, Nifurtimox, which is effective in the acute phase of the disease, but its efficacy in the chronic phase remains controversial. It can also c...

The crystal structures of barium and potassium complexes of (phenylthio)acetic acid (PTAH) have been determined using X-ray diffraction. The barium analogue, [Ba(PTA)2]n(1) is monoclinic, space group C2 with Z = 2, a = 7.219(4), b = 5.894(2), c = 19.272(2) Å, β = 91.57(4)°. [K(PTA)(PTAH)]n(2) ...
