Abstract
Préparation d'un thiophène par l'action de l'H2 S sur une substance organique renfermant de l'oxygène ou du soufre. La substance utilisée est un composé carbonylé ou thiocarbonylé insaturé, en particulier un aldéhyde, thioaldéhyde, cétone ou thiocétone. La réaction a lieu de préférence entre 250 et 500 degrés C sur un catalyseur type alumine renfermant un oxyde alcalin ou alcalino-terreux. Le procédé permet d'obtenir du thiophène non substitué ou substitué avec des rendements et des selectivités élevés, dépassant 70 %.
