Abstract
Invenţia se referă la combinaţiile heterociclice, în particularitate 4-acil-2,3-dihidro-1,4-benzoxazine (BO) sau 4-acil-2,3-dihidrobenztiazine (BT) care pot fi folosite în gospodăria agricolă la protejarea culturilor de acţiunea fitotoxică a erbicidelor. Scopul este crearea combinaţiilor mai eficiente din clasa menţionată conform destinaţiei lor. BO şi BT sunt sintetizate corespunzător din 2,3-di- hidro-1,4-benzoxazină sau 2,3-dihidro-1,4-benztiazină şi clorură de acil, în mediul, de exemplu, de benzol în prezenţa bazei - carbonatului de sodiu la temperatura de cameră. Produsele rezultate sunt substanţe cristalice şi lichide uleioase. Încercarea BO şi BT indică că acţiunea relativă protectoare constituie 63-88% contra 13% pentru combinaţia cunoscută.Tab.:3
