2-Arylnaphth (l, 2-d) oxazoles (111. R= H) and their 5-cyano derivatives (111. R= CN) were synthesized by interaction of 1-amino-2-naphthol and l-amino-2-hydroxy-4- cyanonaphthalene (lb) with aromatic aldehydes. The products exhibited strong violet or bluish-violet fluorescence in solutions. 2-Mercapto-5-cyanonaphth (1, 2-d) oxazole (IV) waa obtained by the action of potassium methyl xanthate on lb. Interaction of 1-nitroso-2- ...
