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 … See more The unimolecular SN1 mechanism proceeds via a carbocation (provided that the carbocation can be adequately stabilized). In the example, the oxygen atom in methyl tert-butyl ether is reversibly protonated. The … See more If the potential carbocation can not be stabilized, ether cleavage follows a bimolecular, concerted SN2 mechanism. In the example, the ether oxygen is reversibly … See more Mechanism Basic ether cleavage is induced by deprotonation in α position. The ether then decomposes into an alkene and an alkoxide. Cyclic ethers … See more SN1 ether cleavage is generally faster than SN2 ether cleavage.
