What type of ligand is thiourea?
Thiourea (tu) is an organic ligand with structure H2NCSNH2.
What is thiourea method?
Thiourea reduces peroxides to the corresponding diols. The intermediate of the reaction is an unstable endoperoxide. Thiourea is also used in the reductive workup of ozonolysis to give carbonyl compounds.
What is the use of thiourea?
Thiourea has a wide range of uses; for example, it is used in the production and modification of textile and dyeing auxiliaries, in the leaching of ores, in the production of pharmaceuticals and pesticides, as a vulcanization accelerator, and as an auxiliary agent in diazo paper.
Is thiourea a bidentate ligand?
1-(2-Pyridyl)-2-thiourea is a bidentate ligand.
What is thiourea found in?
Where is Thiourea found? Thiourea is used as an accelerator in rubber production (e.g. neoprene), and as an antioxidant to photo paper, photographic chemicals, rubber and plastics. It is also found as an additive in etchants, cleaners and polishes.
What is the derivative of thiourea?
Thiourea derivatives are known to accelerate certain reactions such as radical cyclization and the addition of tetramethylsilylcyanide to nitrones via hydrogen-bonding.
What are the elements of thiourea?
An organosulfur compound composed of carbon, nitrogen, hydrogen and sulfur atoms. Its chemical formula is SC(NH2)2. As the name and its composition suggests, thiourea is very much similar to urea.
Is thiourea a pi acceptor?
In addition, thiourea is a very useful nucleophile since it combines the ligand of thiolates (σ-donor) and thioethers (σ-donor and π-acceptor) and is used as a protecting agent to minimize nephrotoxicity following cisplatin treatment (Reedijk 1999).

What is the formula for the compound thiourea?
Thiourea (/ˌθaɪoʊjʊəˈriːə/) is an organosulfur compound with the formula SC(NH 2) 2. It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom, but the properties of urea and thiourea differ significantly.
How is thiourea similar to urea in structure?
It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom, but the properties of urea and thiourea differ significantly. Thiourea is a reagent in organic synthesis. “Thioureas” refers to a broad class of compounds with the general structure (R 1R 2N)(R 3R 4N)C=S.
How is thiourea used as a leaching agent?
A leaching agent for gold leaching and silver leaching can be created by selectively oxidizing thiourea, bypassing the steps of cyanide use and smelting. Another common application for use of thiourea is a common sulfur source for making semiconductor cadmium sulfide nanoparticle. Thiourea is a planar molecule.
