Raman spectral investigation of thiourea complexes
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2009 Spectroscopic properties of metal complexes Of thiourea single crystals (tris thiourea zinc acetate, his thiourea cadmium zinc acetate and his thiourea ammonium chloride)which are non-linear optic materials were investigated by Raman scattering ...

Molecular Structure of Thiourea
The Journal of Physical Chemistry A, 2012The molecular structure of thiourea has been investigated under C(s), C(2), and C(2v) symmetry constraints. At the coupled-cluster level in conjunction with a triple-ζ basis set, only the C(2) conformer has been found to be a real minimum on the potential energy surface.

Nature, 1946
DIFFERENT workers have found the toxicity of thiourea to rats to be very variable1,2,3. Dieke and Richter4 claim that the degree of susceptibility of rats to poisoning by thiourea can be correlated with breed and age. They also suggest that diet plays some part.

Electrostatically Enhanced Thioureas
Organic Letters, 2016A new class of readily prepared thiourea catalysts with one or more positively charged centers and no new hydrogen-bonding sites are exploited in several bond-forming reactions and are orders of magnitude more reactive than Schreiner's thiourea. These findings provide the basis for a new strategy for activating hydrogen-bond catalysts.

Paper Chromatography of Thioureas
Nature, 1953IN the course of a current investigation, it became necessary to separate and identify minute amounts of N-substituted thioureas. Paper chromatography suggested itself as the method of choice for this purpose, and a technique has now been worked out which gives satisfactory and reproducible results on some thirty thioureas investigated, separately or ...

Reaction of thiourea and substituted thioureas with 1,3-dibromopropyne
Russian Journal of General Chemistry, 20084-Bromomethylidene-2-imino(phenylimino, acetylimino)-1,3-thiazolidine hydrobromides and 4-bromomethylidene-2-acetylimino-1,3-thiazolidine are synthesized by the reaction of thiourea, N-phenylthiourea, N,N′-diphenylthiourea and N-acetylthiourea with 1,3-dibromopropyne in glacial acetic acid, absolute methanol, acetonitrile at 20°C or upon heating (60°C).

Biological transformation of thiourea
Archiv f�r Mikrobiologie, 1957Six strains of fungi: two Aspergilli of the A. glaucus group, Penicillium sp. Trichoderma viride, and two unidentified dark fungi, were found able to use thiourea as a source of nitrogen. One of the Aspergilli and the Penicillium showed the best utilization, but the growth was always slow, and no more than 50% (usually much less) of the thiourea ...

Chemistry of Metabolites of Thioureas
1986Thiourea and some monosubstituted thioureas are toxic and tumorogenic while 1,3-diarylthioureas are not. There are strong indications that the biological activity of these compounds is due to oxidation at sulfur followed by reactions in which the sulfur moiety is separated from the rest of the molecule.

The Journal of Chemical Thermodynamics, 1994
Abstract The torsion-effusion technique was used to determine the vapour-pressure dependence on temperature for thiourea (TU); 1-methyl-2-thiourea (MMTU); 1,3-dimethyl-2-thiourea (DMTU); and 1,1,3,3-tetramethyl-2-thiourea (TMTU). The following pressure-against-temperature equations were obtained: for TU(cr), lg( p /kPa) = (11.40 ± 0.25) - (5711 ± 100)
