| Abstrakt: | The acidic cyclization of disalicylamide gave 2-(o-hydroxyphenyl)- and 2-(o-acetoxyphenyl)-4-oxo-1,3-benzoxazinium perchlorates, by reaction of which with hydroxylamine, hydrazines, benzamidine, guanidines, and S-methylisothiourea bis(o-hydroxyphenyl)-1,2,4-oxadiazole, triazoles, and sym-triazines were synthesized. Mono- and bis (o-acetoxyphenyl) triazoles were obtained. |
