Abstract
A találmány tárgya eljárás benzofurán- és benzotiofénszármazék olyanaromás vegyületből történő előállítására, amely aromás vegyületegyrészt legalább 2 szénatomot tartalmazó oldalláncot hordoz, ahol aszénatomok egyike a benzolgyűrűhöz oxigén- vagy kénatomon keresztülkapcsolódik, a másik szénatom karbonsav formában van, másrészt azemlített lánchoz képest orto-helyzetben elhelyezkedő formilcsoportothordoz, amelynek során az utóbbi vegyületet egy karbonsav-anhidridettartalmazó közegben gyűrűzárásnak vetik alá egy bázis, mégpedig fém-vagy ammónium-karbonát és/vagy fém- vagy ammónium-bikarbonátjelenlétében. Aromás kiindulási anyagként előnyösen (I) általánosképletű vegyületet használnak, ahol a képletben R1 jelentésehidrogénatom, egyenes vagy elágazó láncú alkilcsoport, fenilcsoport,amely alkilcsoporttal lehet helyettesítve, vagy halogénfenil-csoport;Z jelentése oxigén- vagy kénatom; R jelentése hidrogénatom vagyhelyettesítő; n értéke 0, 1, 2 vagy 3, előnyösen 0; amikor n értéke 1-nél nagyobb, a két R-csoport és a benzolgyűrű két egymás mellettiatomja telített, telítetlen vagy aromás gyűrűt képezhet.
