The preparation of thiophenes. II. From C5-C7-molecules and carbon disulfide was written by Azizian, Farid;Pizey, James S.. And the article was included in Journal of Chemical Technology and Biotechnology (1979-1982) in 1980.Recommanded Product: 1795-01-3 This article mentions the following:
Alkylthiophenes were prepared in high yields by passing 7 C5-7 alcs., 2-pentanone, or 2-hexanone and CS2 over a promoted Cr-Al2O3 (Girdler G41) catalyst in the vapor phase at 500°. n-Pentane reacted with CS2 at 600° under similar conditions to give 2-methylthiophene and thiophene in 35% and 20% yields, resp. The reaction products were identified by 13C NMR, IR spectroscopy, and gas-liquid chromatog., and the mechanism of the reactions is discussed with particular reference to n-pentane and 2-pentanone. The reaction of 2-pentanol with 13CS2 was used to study the incorporation of the C atom of CS2 into the thiophene ring. In the experiment, the researchers used many compounds, for example, 3-Ethylthiophene (cas: 1795-01-3Recommanded Product: 1795-01-3).
3-Ethylthiophene (cas: 1795-01-3) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Recommanded Product: 1795-01-3
