| titleOfInvention | METHOD FOR PRODUCING SUBSTITUTED 4-PHENYL-THIOPHENES |
| abstract | The invention relates to a process for the preparation of substituted 4-phenyl-thiophenes. Here, phenylacetaldehyde is reacted with a heterocumulene, such as carbon disulfide or an isothiocyanate, in an aprotic solvent with addition of a base, and the resulting geminal dithiolate with a halogen-active CH-acidic compound or first with an alkyl halide and then with a halo-active CH Acids -acid compound or the monosodium salt reacted with a halogen-active CH-acidic compound, then the reaction mixture verduennt, isolated the resulting oil and treated with methanolic sodium methylate solution. The thus synthesized thiophenes can be used as intermediates for organic syntheses. |
