Unformatted text preview: 3 O+ to drive the reaction back to the carbonyl compound and alcohols. 4. Diols can be used to create cyclic acetals . This usually confuses students although it is simply a special case of the same acetal reaction described above. 5. Protecting groups are chemical functions that can reversibly mask a reactive functional group to prevent an unwanted reaction. The protecting group is added prior to the reaction in question, then removed following the reaction in question. 6. Cyclic acetals are good protecting groups for use with Grignard reagents , since the cyclic acetals can be reversibly attached, and they have an sp3 carbon atom that won't react with nucleophiles like carbonyls do....
