What are the possible side-products in the reaction of the prepration od 1,4-di-t-butylbenzene?
Homework Answers
Solution:
When benzene is alkylated in the presence of tert-alkyl halide inthe presence of AlCl3 catalyst, then it forms 1,4-di-tert-butyl benzene as a major product togather with some possible side products.
Side products are:
tert-butylbenzene = C6H5 C(CH3)3
1,2-di-tert-butyl benzene = C6H4 {C(CH)3}2

1. Why is 1,4-di-t-butyl-2,5-dimethoxybenzene the preferred product of this reaction? Why is neither 1,2-di-t-butyl-3,6-dimethoxybenzene nor 1,3-di-t-butyl-3,6-dimethoxybenzene formed as side products? OCH3 OCH3 OCH3 OCH3 1,2-di-t-butyl-3,6-dimethoxybenzene 1,3-di-t-butyl-3,6-dimethoxybenzene 2. 3. 4. Why was the product washed with water? Why was the product washed with methanol? We used t-butyl alcohol to generate t-butyl cation. Suggest two other compounds that could be used to generate the t-butyl cation.
