تحضير أصباغ الآزو لحلقة 1,3,4- ثياديازول-5-ثايول

الملخص EN

Several azo dyes were synthesized through coupling reaction of some substituted phenols and [3- naphthol with diazonium salt of 2-amino- 1,3,4- thiadiazol -5- Thiol.

All the synthesized compounds during this work were characterized using some spectral data (FTIR and UV).

1 2-[2-Hydroxy naphthyl -azo] -1, 3,4 thiadiazol- 5-thiol.

2 2-[4'-Hydroxy-3'-nitro phenyl azo]-1,3,4 thiadiazol-5-thiol.

3 2-[2'-Hydroxy-5'nitro phenyl azo]-l, 3,4 thiadiazol-5-thioi.

4 2-[3',5'-Di methoxv-4'-hydroxy phenyl azo]-1,3,4 thiadiazol-5-thiol.

5 [2'-4f Di hydroxy phenyl azo] -1,3,4 thiadiazol-5-thiol.
