The synthesis of [2.2]paracyclophane derivatives containing tetrathiafulvalene units has been accomplished by the coupling reaction of 4-([2.2]paracyclophan-4-yl)-1,3-dithiol-2-thione in the presence of trimethylphosphite. The 1,3-dithiol-2-thione derivative was in turn synthesized by the regioselective bromination of 4-acetyl[2.2]paracyclophane, then through the corresponding dithiocarbamates ...

The study investigated the corrosion-inhibitory properties of three synthetic triazole Mannich bases on C1018 carbon steel using various electrochemical techniques. inhibitors, namely 4-amino-2-[(4-methylpiperazin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (4MPT), 4-amino-2-[(piperidin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (PPT) and 4-ami...

In the further research and synthesis of highly bioactive 3-methylrhodanine derivatives, preparation benzylidene rhodanines followed by bicyclization to form pyrazole compounds has been undertaken. Using a convenient simple method, twelve have synthesized including six rhodanine derivatives ranging from good excellent yield, with four phenylhydrazone two at low yield. The structures all were el...

Carbon steel (CS) corrosion prevention is a significant problem in the industry. The development of an effective protection strategy popular research area. In this work, three thiazole derivatives (3-(2-methoxyphenyl)−4-methylthiazol-2(3H)-thione (P1), 3-phenyl-4-methylthiazol-2(3H)-thione (P2) and 3-(2-methyl-phenyl)−4-methylthiazol-2(3H)-thione (P3)) were used 0.5 M H2SO4 solution for CS miti...

The title compound, C(20)H(17)N(3)O(2)S(2), was synthesized by the reaction of 2-(1,5-diphenyl-1H-pyrazol-3-yl-oxy)acetic acid and thia-zolidine-2-thione. The C-linked benzene ring, N-linked benzene ring and thia-zolidine-2-thione ring are twisted 31.33 (2), 62.87 (1) and 82.71 (2)°, respectively, from the plane of the bridging 1H-pyrazole ring. The phenyl rings are oriented at a dihedral angle...

The title compound, C28H33N2S2P, adopts the thione tautomeric form, as supported by the C-S distance [1.6744 (18) Å]. The Schiff base exhibits an E conformation about the C=N bond but a Z conformation about the C-N bond. The terminal chain is disordered over two sets of sites with an occupancy ratio of 0.732 (3):0.268 (3). In the crystal, pairs of N-N-H hydrogen bonds between the thione groups ...

Reactions of imidazolidine-2-thione (Imt), 1,3-diazinane-2-thione (Diaz) and 1,3-diazipane-2thione (Diap) with mercury(II) selenocyanate in acetonitrile resulted in formation of 2 : 1 complexes. Both solid state and solution NMR, confirm the exocyclic sulfur atom to be the donor in all cases. Hg shielding tensors and anisotropies were calculated from the solid-state NMR spectra. Based on the so...

The asymmetric unit of the title compound, {(C34H28FeP2)[Au(C5H8NS2)]2}, comprises half a mol-ecule, with the full mol-ecule being generated by the application of a centre of inversion. The independent Au(I) atom is coordinated by thiol-ate S and phosphane P atoms that define an approximate linear geometry [S-Au-P = 169.35 (3)°]. The deviation from the ideal linear is traced to the close approa...

Treatment of 1,3-bis(3'-butylimidazolyl-1'-yl)benzene diiodide with elemental sulfur in the presence of a base produced a bis(N-heterocyclic thione) (NHT) pincer ligand precursor. Its reaction with PdCl2(CH3CN)2 produced chloro[1,3-bis(3'-butylimidazole-2'-thione-κ-S)benzene-κ-C]palladium(ii), a 6,6-fused ring SCS-NHT palladium pincer complex. This air stable compound is, to our knowledge, the ...

Four coordinate tetrahedral (Pd0 and Pt0) and square planar (Rh+ and Ir+) complexes of triphenyl phosphine and 1-benzyl tetrazoline-5-thione have been prepared and characterised on the basis of elemental analysis and spectroscopic data (IR, UV-vis, 1HNMR). Bonding of tetrazole ligand occurs through thione tautometric form. Determination of oxidation state of central metal atom in the complexes ...
