Iodine-mediated oxidative N–S bond formation: a facile one-pot synthetic approach to 1,2,4-benzothiadiazine 1,1-dioxides under transition metal-free conditions J. Sulfur Chem. (IF 2.2) Pub Date : 2023-01-11 Sümeyye Buran Uğur, Şengül Dilem Doğan
Benzothiadiazine 1,1-dioxide derivatives are widely used because of their diverse biological activities and medicinal prospects. In this study, iodine-oxone mediated oxidative N–S bond formation reaction was described. This new and transition-metal-free approach allows for the convenient synthesis of a variety of 1,2,4-benzothiadiazine 1,1-dioxides from readily available urea derivatives under very

Aqueous microwave assisted novel synthesis of isothiocyanates by amine catalyzed thionation of isocyanides with Lawesson's reagent J. Sulfur Chem. (IF 2.2) Pub Date : 2023-01-09 Sodeeq Aderotimi Salami, Vincent J. Smith, Rui W. M. Krause
A green and sustainable chemistry approach for organic synthesis is described here, which involves microwave exposure of reactants in the presence of water. A general, practical, and highly efficient protocol for the preparation of a broad range of functionalized isothiocyanates has been developed from their corresponding isocyanides using Lawesson's reagent and catalytic amount of amine bases, particularly

Synthesis, spectroscopic characterization, biological activity, and conducting properties of functionalized Ni(II) dithiocarbamate complexes with solvent extraction studies of the ligands J. Sulfur Chem. (IF 2.2) Pub Date : 2022-12-20 Vinay Kumar Maurya, Lal Bahadur Prasad, Anupam Singh, Kunal Shiv, Akhilesh Prasad
A series of new nickel(II) dithiocarbamate complexes of general formula [M L2], (where L = benzyl(4-fluorobenzyl)carbamodithioate (L1), benzyl(4-cyanobenzyl)carbamodithioate (L2), ethyl(4-methylbenzyl)carbamodithioate (L3), (4-methoxybenzyl) (naphthalen-1-ylmethyl)carbamodithioate (L4) and ethyl(4-methoxybenzyl)carbamodithioate (L5)) have been synthesized, and characterized via elemental analysis,

The chemical reaction of thioindole and [20] fullerene and the use of DFT to estimate some quantum chemical descriptors J. Sulfur Chem. (IF 2.2) Pub Date : 2022-12-10 Ahmad AB Yosef Kinani, Evan Abdulkareem Mahmood, Seyed Mohammad Shoaei, Mohammad Reza Poor Heravi, Sepideh Habibzadeh, Abdol Ghaffar Ebadi, Issa Amini, Esmail Vessally
In this study, the solvent effects are probed on the chemical reaction of the (E)-3-thiophene-2-yl-indoline-2-thione (I) and [20] fullerene, and the resulted complex (Ia) via the density functional theory (DFT). To characterize the synchronicity of the reaction and its correlation with activation energy, we estimated the energy barrier of transition states (ETS1≠ and ETS2≠) in the used solvents. The

Platinum(II) and palladium(II) complexes mediated by β-hydroxy-dithioesters ferrocenyl derivatives: synthesis, characterization and antiproliferative activity J. Sulfur Chem. (IF 2.2) Pub Date : 2022-12-07 Micheal K. Farh, Ikrame Louzi, Hassan Abul-Futouh, Helmar Görls, Norman Häfner, Ingo B. Runnebaum, Wolfgang Weigand
Ferrocene and its derivatives compounds have shown a significant role in medicinal organometallic chemistry as an antiparasitic or antibacterial. Therefore, we herein report on the utilization of dithioesters ferrocenyl derivatives as proligands for the synthesis of heteroleptic platinum(II) and homoleptic palladium(II) complexes bearing a conserved O,S binding moiety. The resulting complexes [Pt(L1)(DMSO)Cl]
