Webentry 1). The normal reduction product, hydrocinnamyl alcohol, predominated at 66% yield along with 7% of the triethyl silyl ether. No reduction occurs in the absence of either TMSOMs or BF 3•OEt 2 which further supports the idea that BF 2OMs•OEt was responsible for moderating the ester to ether reduction.

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 protonated.
