For example, the carboxylic acid can …
WebMechanism of the Fischer Esterification Addition of a proton (e.g.: p -TsOH, H 2 SO 4) or a Lewis acid leads to a more reactive electrophile. Nucleophilic attack of the alcohol gives a tetrahedral intermediate in … The primary advantages of Fischer esterification compared to other esterification processes are based on its relative simplicity. Straightforward acidic conditions can be used if acid-sensitive functional groups are not an issue; sulfuric acid can be used; weaker acids can be used with a tradeoff of longer reaction times. Because the reagents used are "direct," there is less environmental impact in terms of waste products and harmfulness of the reagents. Alkyl halide…
