A review on the chemistry, coordination, structure and biological properties of 1-(acyl/aroyl)-3-(substituted) thioureas
Aamer Saeed, Ülrich Flörke, Mauricio F. Erben · 11 Sep 2013
This review provides an overview of the chemistry, structure and potential applications of 1- (acyl/aroyl)-3-(mono-substituted) and 1-(acyl/aroyl)-3,3-(di-substituted) thioureas, with general formula R1C(O)N(1)HC(S)N(3)R2R3. In recent years, the title compounds have found extensive applications as ligands in coordination chemistry. The effect that nitrogen substituents exert on the intra- and intermolecular hydrogen-bonding interactions is discussed, including their role…
Microbiological disproportionation of inorganic sulfur compounds
Kai Finster · 21 Jun 2008
The disproportionation of inorganic sulfur intermediates at moderate temperatures (0-80 °C) is a microbiologically catalyzed chemolithotrophic process in which compounds like elemental sulfur, thiosulfate, and sulfite serve as both electron donor and acceptor, and generate hydrogen sulfide and sulfate. Thus the overall process is comparable to the fermentation of organic compounds such as glucose and…
Thioesters synthesis: recent adventures in the esterification of thiols
Mosstafa Kazemi, Lotfi Shiri · 1 Sep 2015
Thioesters are important class of organosulfur compounds that play a fundamental role in the construction of pharmaceutical, biological, industrial and natural products. In this respect, thioesters synthesis is one of the most important tasks in organosulfur chemistry. The esterification of thiols is the best and most common strategy for the synthesis of thioesters. During the…
Application of carbon nanostructures toward SO<sub>2</sub> and SO<sub>3</sub> adsorption: a comparison between pristine graphene and N-doped graphene by DFT calculations
Ali Shokuhi Rad, Mehri Esfahanian, Sina Maleki et al. · 20 Jan 2016
We studied the adsorption of SOx (x = 2,3) molecules on the surface of pristine graphene (PG) and N-doped graphene (NDG) by density functional theory (DFT) calculations at the B3LYP/6-31G(d) level. We used Mulliken and NBO charge analysis to calculate the net charge transfer of adsorbed SOx on pristine and defected graphene systems. Our calculations…
Synthesis and biological activity of natural thiazoles: An important class of heterocyclic compounds
M.V.N. De Souza · 1 Aug 2005
The class of heterocyclic compounds known as thiazole is found in many natural and synthetic products with a wide range of pharmacological activities, such as antiviral, anticancer, antibacterial, antifungal, anticonvulsant, antiparkinsonian and anti-inflammatory activities that can be well illustrated by the large number of drugs in the market containing this function group. Due to its…
