The direct reduction of esters to their corresponding ethers has been achieved using the Lewis acid BF 2 OTf·OEt 2 generated via anionic redistribution between TMSOTf and BF 3 ·OEt 2 with triethylsilane acting as the reducing agent. Isolated yields of up to 71% have been obtained with the corresponding alcohol as the only side product.
A NOVEL METHOD FOR THE PREPARATION OF SYMMETRICAL AND UNSYMMETRICAL ETHERS. TRITYL PERCHLORATE PROMOTED REDUCTION OF CARBONYL COMPOUNDS WITH TRIETHYLSILANE
In the presence of a catalytic amount of trityl perchlorate, symmetrical ethers are prepared from aldehydes and triethylsilane, and unsymmetrical ethers are also obtained from carbonylcompounds, alkoxytrimethylsilanes and triethylsilane, in good yields, respectively.
