CHARACTERISTICS OF THE ALKOXYLATION OF HALOGENO-6-OXO-6H-ANTHRAISOXAZOLES
The alkylation of 6-oxo-6H-anthraisoxazoles containing a chlorine or bromine atom at position 3 and also a bromine at position 5 takes place with substitution of the halogen or hydrogen, depending on the structure of the alkoxide ion and the type of halogen.

REACTION OF 6H-6-OXO--3(5)-HALOGENOANTHRAISOXAZOLES WITH INORGANIC NUCLEOPHILES
The reaction of 6H-6-oxo-3(5)-halogenoanthraisoxazoles with sodium azide in DMFA and also the potassium fluoride in acetonitrile in the presence of crown ethers leads to nucleophilic substitution of the halogen by the azide and fluoride ion respectively.
