Several 2-substituted 4,6-diphenyl-1,3-thiazin-1-ium salts I (R = MeS, Ph, Me₂N, 4-Me₂NC₆H₄; X = ClO₄, BF₄) were accessible conveniently by the reaction of benzoylphenylacetylene with RCSNH₂ in the presence of HX. The reactivity of I (R = MeS, X = ClO₄) (II) toward nucleophiles, such as active methylenes and various amino compounds, was investigated. Active methylenes and monofunctional primary amines attacked the 2-position of the thiazinium ring to afford 2-(disubstituted methylene)- and 2-(substituted imino)-4,6-diphenyl-2H-1,3-thiazines, resp. On the other hand, bifunctional nucleophiles, such as hydrazine and hydroxylamine, reacted at the 4- and 6-positions of II to give 3,5-diphenylpyrazole and isoxazole, resp.

Pantel, Siegbert published the artcileCatalytic-kinetic determination of substituted thioureas and thioacetamide by an absorptiostat method with bromopyrogallol red/hydrogen peroxide as the indicator reaction, Related Products of catalysis-chemistry, the publication is Analytica Chimica Acta (1984), 158(1), 85-91, database is CAplus.

In the absorptiostat method described, the concentration of the dye in the bromopyrogallol red/H₂O₂ reaction is kept very low and constant by the automatic addition of increments of bromopyrogallol red solution This is used in aqueous solutions at pH 4.0 to determine the catalyst thiourea, N-methylthiourea, N‘-allylthiourea, and thioacetamide in the 0.1-1 mmol L^-1 range with only 0.5-mL samples. The catalytic activities of another nine substituted thioureas are described; they depend on the kind of N-substituents as has been shown before for the NaN₃/I₂ reaction, but the sequence of activities for different compounds is quite different.

Densities of dilute aqueous solutions of 1-monomethyl-2-thiourea and 1,1,3-trimethyl-2-thiourea have been measured using an Anton Paar DMA 5000 M vibrating-tube densimeter. The apparent molar volumes and expansibilities (down to infinite dilution) have been calculated from the obtained d. data. The experiments have been performed in the temperature range between (278.15 and 318.15) K, with a step of 10 K, at p ? 0.1 MPa. The influence of a nature of methyl-N-sited substituents on the structure-packing properties of aqueous thioureas has been discussed. A possibility to estimate the standard (limiting apparent or partial) molar volumes for asym. substituted 1,1-dimethyl-2-thiourea in water has been considered, too.

Bianchi, Alberto published the artcileUltrastructural studies of the effects of Allium sativum on phytopathogenic fungi in vitro, COA of Formula: C3H8N2S, the publication is Plant Disease (1997), 81(11), 1241-1246, database is CAplus and MEDLINE.

A study was made of the effects of garlic on the development of mycelium in the following phytopathogenic fungi: Fusarium solani (Mart.) Sacc., Rhizoctonia solani Kuhn, Pythium ultimum Trow var. ultimum, and Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi and Cav. A suspension of micronized garlic powder, which has volatile organic compounds mainly consisting of linear chain aldehydes, allyl sulfides and disulfides, was used for the trials. Mycelial development of the fungi was strongly inhibited at the maximum concentration of the aqueous extract tested (100 mL/L); however only the growth of P. ultimum var. ultimum was entirely blocked. Transmission and SEM revealed cytomorphol. alterations of the hyphae treated with garlic. R. solani and C. lindemuthianum hyphae appeared especially collapsed, while those of F. solani were less damaged, although thinner than the control hyphae. A general increase in vacuolization was also observed, with consequent reduction in the cytoplasm of the treated fungal cells. R. solani also revealed a thickening of the cell wall, whereas C. lindemuthianum revealed a singular accumulation of osmiophil bodies immediately under the cell membrane.

Wang, Hai-su published the artcileQuality characteristics of black garlic with differet processing procedures, Recommanded Product: 1,1-Dimethylthiourea, the publication is Xiandai Shipin Keji (2014), 30(7), 230-236, 257, database is CAplus.

In this study, fresh garlic from Jinxiang was fermented to black garlic by -18¡ãC pretreatment combined with variable temperature fermentation for the first time. The total color difference, water content, texture, reducing sugar content, total phenol content, free amino acid content, volatile components and sensory indexes of black garlic were determined in order to compare the quality characteristics of lab-prepared fermented black garlic (FBG) and three kinds of com. black garlic made by traditional processing. The results indicated that the fermentation period by the new processing method with frozen pretreatment decreased, which was shortened from 60-90 days to 15 days and FBG made by the new processing method was similar or better than the com. black garlic by traditional processing in terms of sensory indexes, nutrition and functional components. The reducing sugar content, total phenol content, free amino acid content of FBG reached to (48.50 ¡À 0.44) ¡Á 10^-2 g/g, 10.44 ¡À 0.53 mg/g, (54.90 ¡À 0.61) ¡Á 10^-2 mg/g, resp., by the new method. At the same time, the contents of 17 kinds of amino acid and volatile components are equal or higher than those of the com. black garlic. Therefore, the new processing technol. for FBG shortened the fermentation period, and ensured the quality of black garlic products. These results provided references for black garlic processing industry in China.
