1,4-Dimethoxybenzene organic chem lab
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.

For a Friedel-Crafts alkylation reaction between 1,4-dimethoxybenzene with 3-methyl-2-butanol and sulfuric acid what product was formed in this reaction? Use a discussion of the reaction mechanism, IR, and NMR data to justify your conclusion. A figure should be included to aid in the discussion of the reaction mechanism.

Give a detailed mechanism including all resonance isomers for intermediates (show electron flow) for the Friedel-Crafts reaction done in the lab. NOTE: It is likely the mechanism from reactants to only 1-t-butyl-2,5-dimethoxybenzene is on the blackboard in class. I want a complete mechanism showing all steps and resonance isomers for the synthesis of the dialkylated product!

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
