Hydrolysis of nitrile to carboxylic acid mechanism-acidic conditions.Carboxylic acid - Reduction, Reactivity, Synthesis: Although carboxylic acids are more difficult to reduce than aldehydes and ketones, there are several agents that accomplish this reduction, the most important being lithium aluminum hydride (LiAlH4) and borane (BH3). The product is a primary alcohol (RCOOH → RCH2OH). There are no known general …The mechanism begins with the protonation of the nitrile to make it more electrophilic to nucleophilic water. Once the water has reacted with the nitrile carbon, proton transfers occur to produce a resonance stabilized intermediate. Water acts as a weak base to deprotonate the carbonyl to form the amide which is hydrolyzed to the carboxylic acid.Two other useful procedures for preparing carboxylic acids involve hydrolysis of nitriles and carboxylation of organometallic intermediates. As shown in the following diagram, both methods begin with an organic halogen compound and the carboxyl group eventually replaces the halogen.
