Ether cleavage refers to chemical substitution reactions that lead to the cleavage of ethers. Due to the high chemical stability of ethers, the cleavage of the C-O bond is uncommon in the absence of specialized reagents or under extreme conditions. In organic chemistry, ether cleavage is an acid catalyzed nucleophilic substitution reaction. Depending on the specific ether, cleavage can follow either SN1 or SN2 mechanisms. Distinguishi… WebThe reaction is especially useful for cleavage of homoallylic ethers and the removal of terminal allyl and propargyl groups. C. Matt, F. Kölblin, J. Streuff, Org.
