Abstract

Riešenie sa týká halagénacetylénov 5-nitro-2-tiofénu vzorca I, kde X je chlór, bróm alebo jód, novej skupiny acetylénojvých derivátov 5-nitro-2-tiofénu, s možným použitím ako antibakteriálnych preparátov a reaktívnych komponentov pře přípravu nových antibiotik. Podstata spósabu přípravy uvedených látok spočívá v tom, že na deriváty 5-nitro- -2-tienylacetylénu vzorca II, kde M je vodík, striebra, meď alebo magnézium,bromid, sa pósobí halogénom v prostředí organických rozpúšťadiel ako sú aromatické kvapalné uhlovodíky, étery, deriváty octovej kyseliny, halogénované rozpúšťadlá vo- vodě a/ /alebo v ich zmesiach s vodou za přítomnosti bázických katalyzátorov typu uhličitanov a hydroxidoví alkalických kovov v rozmedzí teplůt —20 °C až +150 °C.
