2-(2-Hydroxyphenyl)benzothiazole synthesis
- Product Name:2-(2-Hydroxyphenyl)benzothiazole
- CAS Number:3411-95-8
- Molecular formula:C13H9NOS
- Molecular Weight:227.28
Yield: 98%
Reaction Conditions:
with cadmium sulphide in methanol at 20; for 0.333333 h;Catalytic behavior;Irradiation;
Steps:
Catalytic procedure
General procedure: In the experimental procedure for catalytic reaction, amixture of aldehyde (3 mmol), 2-aminothiophenol (3 mmol) and CdSnanosphere (5 mg) was taken in a 100 ml double walled quartz beaker flaskhaving water inlet and outlet to maintain the temperature of the reactionvessel at room temperature in methanol (20 ml). The beaker was exposed tovisible light under stirring condition for the required time period (Table 3).After completion of the reaction (monitored by TLC and GC), methanol wasevaporated by rotary and the product was dissolved in dichloromethane. Thecatalyst was separated from the reaction mixture by centrifugation.Dichloromethane was then evaporated to dryness and the product waspurified by column chromatography using silica gel G60.
