Alcohol to sulfonate
WebMar 16, 2024 · Some examples of alcohol substitution reactions using this approach to activating the hydroxyl group are shown in the following diagram. The first two cases serve to reinforce the fact that sulfonate ester derivatives of alcohols may replace alkyl halides in a variety of S N 2 reactions. WebThe most exciting class of reagents is sulfonyls. They react with the alcohols to form corresponding mesylates, tosylates, or triflates to improve their reactivity in an S N 2 reaction. In these species, resonance stabilization is inherent to the sulfonyl group.

WebActivation of an alcohol towards nucleophilic displacement with halide ion can be achieved by converting it to a sulfonate ester, commonly tosylate ( p-toluenesulfonate), mesylate (methanesulfonate) or triflate (trifluoromethanesulfonate) (Scheme 9 ). These are readily prepared and are often stable enough to be isolated and purified.
