17890-56-1 - Reference Information
| introduction | 1-benzothiophene -2-methanol is a thick body of benzene ring and thiophene, melting point 98-101 ℃, boiling point 324°C at 760 mmHg, density 1.294g/cm3(25 ℃), soluble in ethanol, soluble in benzene, ethyl ketone, ether and other organic solvents. Benzothiophene derivatives are an important class of sulfur-containing benzo heterocyclic compounds. In recent years, the research on benzothiophene and its derivatives has attracted more and more attention. Many research papers have been published every year in organic synthetic chemistry, medicinal chemistry, material chemistry and other disciplines, which has become a promising research direction. |
| use | 1-oxy malenonitrile is a typical malononitrile derivative, which is a common herbicide and growth regulator. |
| Preparation | So far, there have been many methods for the synthesis of benzothiophene skeletons, including α-The intramolecular cyclization of aryl ketones, o-alkynyl (alkenyl) thiophenol and aryl sulfide, direct functionalization of benzothiophene skeletons, and other methods. Direct synthesis of benzothiophene derivatives through simple and easy-to-obtain thiophenol is an effective and practical method. The reaction formula of 1-benzothiophene-2-methanol is shown in the figure below. |
