Reductive Etherification via Anion-Binding Catalysis
Reductive condensations of alcohols with aldehydes/ketones to generate ethers are catalyzed by a readily accessible thiourea organocatalyst that operates in combination with HCl. 1,1,3,3-tetramethyldisiloxane serves as a convenient reducing reagent. This strategy is applicable to challenging substrate combinations and exhibits functional group tolerance. Competing reductive homocoupling of the carbonyl component is suppressed.

Reduction of esters to ethers utilizing the powerful lewis acid BF 2OTf·OEt2
The direct reduction of esters to their corresponding ethers has been achieved using the Lewis acid BF2OTf·OEt2 generated via anionic redistribution between TMSOTf and BF3·OEt 2 with triethylsilane acting as the
