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...

Consider the following reaction: OH Н4С H,SO CH3 + ОН A Show the complete mechanism for the following transformations. Make sure to show all arrows depicting the movement of electrons. The above reaction (using acid and heat) causes a number of unwanted side products to form (a big mess). Propose a better synthesis for the product using the same starting materials. Show the reagents and intermediate steps to complete the synthesis: ОН. HzC...
