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.

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...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
