Bismuth Trichloride Catalyzed Efficient Reductive Etherification of Carbonyl Compounds with Alcohols: A Novel Method for Preparation of Symmetrical and Unsymmetrical Ethers
The reductive homocoupling of a carbonylcompound and heterocoupling of a carbonylcompound with a non-protected alcohol were both effected smoothly at room temperature with triethylsilane in the presence of a catalytic amount of bismuth trichloride to afford the corresponding ethers in good yields.

Various alcohol silyl ethers were readily and efficiently transformed into the corresponding alkyl ethers in high yields by the use of aldehydes combined with triethylsilane in the presence of a catalytic amount of iron(III) chloride.
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.
