BTBK Reaction Mechanism
The BTBK reaction proceeds through a series of steps:
- Protonation of the alkene: The acid catalyst protonates the alkene, forming a carbocation intermediate.
- Addition of the first ketone/aldehyde molecule: The carbocation intermediate reacts with one molecule of the ketone or aldehyde, forming a new carbocation intermediate.
- Addition of the second ketone/aldehyde molecule: The second molecule of the ketone or aldehyde reacts with the carbocation intermediate, forming a ketal or acetal product.
Applications of BTBK Reaction
The BTBK reaction is used in a variety of chemical applications, including:
- Protection of carbonyl groups: Ketals and acetals are stable functional groups that can be used to protect carbonyl groups from unwanted reactions.
