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).

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.

Matrix and ab initio infrared spectra of thiourea and thiourea-d4
Vibrational Spectroscopy, 1998Abstract The FTIR spectrum of thiourea and thiourea-d 4 isolated in argon and nitrogen matrices are presented for the first time and discussed in terms of normal modes predicted by ab initio calculations. Vibrational frequencies, IR intensities and isotopic shifts obtained from the density functional B3-LYP/6-31+G(2d,p) calculations show the most ...

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)

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 ...
