Cleavage of Ethers

Abstract: The scope and limitations of reagents for the cleavage of ethers are discussed. The reagents are conveniently classified in the five main headings. Selectivity patterns of some of the reagents are discussed in cases where sufficient data has been given in the literature. 1. Introduction 2. Acidic Reagents 2.1. Bronsted Acids 2.2. Lewis Acids 3.
