Fly-ash:H2O catalyzed aqueous phase cyclization of chalcones: synthesis of some substituted pyrazole-1-carbothioamides and spectral correlations in 3-(3,4-dimethylphenyl)-5-(substituted phenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamides was written by Thirunarayanan, G.;Sekar, K. G.. And the article was included in Organic Chemistry: An Indian Journal in 2013.Recommanded Product: 3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one This article mentions the following:
Substituted 1-thiocarbamoyl pyrazolines I (R1 = Me, Ph, 4-MeOC6H4, 2-thienyl, 3,4-Me2C6H3, etc.; R2 = Ph, 4-MeOC6H4, 2-furyl, 2-thienyl, etc.) were synthesized by solvent-free aqueous phase fly-ash:H2O catalyzed cyclization of chalcones R1C(O)CH:CHR2 and thiosemicarbazide in higher than 75% yields. The spectral data of the compounds I (R1 = 3,4-Me2C6H3; R2 = Ph, 4-MeOC6H4, 2-BrC6H4, 4-BrC6H4, etc.) was correlated using single and multi-linear regression anal. In the experiment, the researchers used many compounds, for example, 3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one (cas: 3988-77-0Recommanded Product: 3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one).
3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one (cas: 3988-77-0) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Recommanded Product: 3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one
