Alcohols in nucleophilic substitution reactions

But we want to use alcohols in nucleophilic substitution reactions because they are easily made. The simplest answer is to protonate the OH group with strong acid. This will work only if the nucleophile is compatible with strong acid, but many are. The preparation of f-BuCl from f-BuOH simply by shaking it with concentrated HC1 is a good example. This is obviously an SnI reaction with the t-butyl cation as intermediate.
