Final Project Spring 2011: Part VI

The lab report for the final project was submitted as a JOC style article. The students had been writing parts of their lab reports in scientific article format during the semester: Abstract, Introduction, Results and Discussion, Conclusion, Experimental Section, and of course References. This was the first time I had given this type of assignment […]

Final Project Spring 2011: Part V

The fourth synthesis project started with the dehydration of cyclohexanol. We had performed the dehydration of 2-methylcyclohexanol during the Fall semester. The resulting cyclohexene was oxidized by hydrogen peroxide in the presence of a phase-transfer catalyst. This reaction was featured in a 2000 JCE article. There was some unreacted cyclohexanol with the cyclohexene but that […]

Final Project Spring 2011: Part IV

The third project started with the synthesis of an azo dye that we had performed earlier in the semester. The combination of 4-aminosulfonic acid and 2-naphthol yields 4-(2-hydroxy-1-naphthylazo)benzenesulfonic acid which is also known as acid orange 7. The phenolic hydroxyl group was acetylated with acetic anhydride in a reaction which is similar to the one […]
