Which of the reagents listed below will convert benzene to methyl benzoate? Which of the reagents listed below will convert benzene to methyl benzoate? General Mechanism For Nitration Of Benzene When adding the mixture of acids to the ester, it is important to keep the temperature of the reaction below 15 °C. The -COOCH3 group is a meta director (it’s deactivating also but you don’t need that for this problem). A large concern over the use of sodium benzoate is its ability to convert to benzene, a known carcinogen. Lesson organisation.

Which of the reagents listed below will convert benzene to methyl benzoate? Which of the reagents listed below will convert benzene to methyl benzoate? General Mechanism For Nitration Of Benzene When adding the mixture of acids to the ester, it is important to keep the temperature of the reaction below 15 °C. The -COOCH3 group is a meta director (it’s deactivating also but you don’t need that for this problem). A large concern over the use of sodium benzoate is its ability to convert to benzene, a known carcinogen. Lesson organisation.
