Abstract:
Thioureas or thiourea derivatives as organosulfur compounds are one of the most widely used ligands in different applications as we are going to discuss it extensively such as in coordination chemistry by involving them to rich sources of N, O and S atoms coordinating through S atom, S and O atoms in benzoyl derivatives or S, O and N atoms in pyridyl hetrocylic benzoyl derivatives. These hard and soft donor sites facilitate the bonding between thiourea free ligand and metal ion through one or more to make ligands behave as mono, bi or multidentate ligands to form huge and stable series of the

Abstract: The thiourea is an interesting inorganic matrix modifier. Recently, researchers are focusing on growing metal complexes of thiourea crystals. Some of the examples are bis thiourea zinc chloride (BTZC) , tetrakis thiourea potassium iodide (TTPI) , tetra thiourea potassium iodide (TTPI) , tetra thiourea cobalt chloride (TTCoC) , bis thiourea cadmium chloride (BTCC) etc., G.Anand et al , S.Gopinath et al and M.Mariappan et al have reported the growth and characterization of metal complexes of urea thiourea.

Complexes of cell-THPC-thiourea-ADP with Mg2+ have been prepared. The thermal stability and smoke suspension of the samples are determined by TG, DTA and cone calorimetry. Experimental data show that for the complexes of cell-THPC-thiourea-ADP with Mg2+, thermal decomposition temperatures are higher than those of cell-THPC-thiourea-ADP, which shows these metal ions can increase the thermal stability of cell-THPC-thiourea-ADP. The cone calorimetry data indicate that the metal ions greatly decrease the smoke, CO and CO2 generation of cell-THPC-thiourea-ADP, which can be used as smoke suppressant

In this work, two thiourea ligands bearing a phosphine group in one arm and in the other a phenyl group (T2) or 3,5-di-CF3 substituted phenyl ring (T1) have been prepared and their coordination to Au and Ag has been studied. A different behavior is observed for gold complexes, a linear geometry with coordination only to the phosphorus atom or an equilibrium between the linear and three-coordinated species is present, whereas for silver complexes the coordination of the ligand as P^S chelate is found.

Abstract:
Benzothiazole derivatives are a class of privileged molecules due to their biological activity and pharmaceutical applications. One route to these molecules is via intramolecular cyclization of thioureas to form substituted 2-aminobenzothiazoles, but this often requires harsh conditions or employs expensive metal catalysts. Herein, the copper(II)- and gold(III)-mediated cyclizations of thioureas to substituted 2-aminobenzothiazoles are reported.

Abstract:
Reaction of two equivalents of the bulky 1,3-bis(2,6-diethylphenyl)thiourea ligand (L) with MX (being M = Cu+, Ag+; and X = Cl−, Br−, I−) in acetonitrile afforded neutral complexes of the type [MXL2] [CuClL2].2CH3CN (1a); [CuBrL2].2CH3CN (1b); [CuIL2] (1c): [AgClL2] (2a); [AgBrL2] (2b) and [AgIL2] (2c). The two aromatic groups in free ligand were found to be trans with respect to the thiourea unit, which was a reason to link the ligand molecules via intermolecular hydrogen bonding. Intramolecular hydrogen bonding was observed in all metal complexes. The copper complexes 1a and 1b are acetonitr

In such complexes, the uranyl ions are commonly coordinated by the “hard” O,N,O or N,N,N donor atom sets of the central ligand unit and the lateral sulfur donor atoms remain uncoordinated. Their individual structures, however, depend on the reaction conditions, particularly on the equivalents of NEt3 used. An unprecedented, selective hydrolysis

This research thesis considers the design and synthesis of a range of thiourea bipyridyl complexes and their use as anion binding receptors. A range of isothiocyanate precursors were synthesised from a reaction employing carbon disulphide. These precursors were then coupled with 5-aminomethyl-2,2’-bipyridine to prepare a group of novel bipyridyl Iigands each containing at least one thiourea functionality. Three of the Iigands were successfully reacted with [Re(CO)5Br] to create three dinuclear rhenium{l} complexes. All of the Iigands were successfully reacted with [Ru(bpy)2Cl2] to yield eight

The results of the research show that on irradiation, TGA can regenerate an additional amount of OH radicals, thus contributing to the intensification of water self-purification processes.
