• Acid catalysis is required for this reaction. Often, mercury trifluoroacetate (Hg(OCOCF3)2) is used as a catalyst for the reaction generating an ether with Markovnikov regiochemistry.
• The acidity is strong enough to protonate hydrocarbons and high-silica zeolites are used in acid catalysis processes such as fluid catalytic cracking in petrochemical industry.
• Itaconic acid anhydride is isomerized to citraconic anhydride, which is hydrolyzed and the resulting acid further isomerized under acid-catalysis to give mesaconic acid.
• Although general-acid catalysis for breakdown of the First and Second tetrahedral intermediate may occur by the path shown in the diagram, evidence supporting this mechanism with chymotrypsin has been controverted.
• Active site engineering resulted in loss of the enzyme's ability to form hopanoids, but enabled Brønsted acid catalysis for the stereoselective cyclization of the monoterpenoids geraniol, epoxygeraniol, and citronellal.

• In acid catalysis and base catalysis, a chemical reaction is catalyzed by an acid or a base.
• Traditionally an acidic catalyst in protic solvent was employed with heating, however the reaction has been shown to work in aprotic media in superior yields and sometimes without acid catalysis.
• For example, hexanoyl chloride 1 can be brominated in the alpha-position by NBS using acid catalysis.
• The reaction proceeds by acid catalysis where the double bond in 7 opens to form the carbocation 8.
• Carbonyl ylides can be synthesized by acid catalysis of hydroxy-3-pyrones in the absence of a metal catalyst.

• The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water.
• In the DuPont route, aniline is converted to diphenyltriazine, which is then converted by acid-catalysis to 4-aminoazobenzene. Hydrogenation of the latter affords PPD.
• Polyamides can also be synthesized from dinitriles using acid catalysis via an application of the Ritter reaction.
•   However, evidence for similar general-acid catalysis of the k2 reaction (Tet2) has been controverted; apparently water provides a proton to the amine leaving group.
