WebFeb 5, 2024 · The results from this study demonstrate that the chemical cleavage of thioether bond by desulfuration is simple, efficient, and specific. This technique is useful in characterization of metabolism on the payload of ADC to provide guidance for improvement of its biopharmaceutical profile. 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 … 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 protonated. The halide ion (here bromide) then nucleophilically attacks the sterically less … See more Mechanism Basic ether cleavage is induced by deprotonation in α position. The ether then decomposes into an See more SN1 ether cleavage is generally faster than SN2 ether cleavage. However, reactions that would require the formation of unstable carbocations (methyl, vinyl, aryl or primary carbon) proceed via SN2 mechanism.
