✦ Synopsis

A Mild, Efficient, and Selective Method for the Desilylation of More Common Trialkylsilyl Ethers by Cerium(III) Chloride Heptahydrate and Sodium Iodide in Acetonitrile.

-Conditions A) are found to be efficient for the high-yielding deprotection of common trialkylsilyl ethers. The method tolerates the presence of a variety of functional groups such as acetate, benzyl and tetrahydropyranyl ethers. Interestingly, by carefully adjusting the reaction conditions compounds such as (IX) bearing different silyloxy groups can be deprotected highly selectively. -(BARTOLI, G.; BOSCO,
