The hydrofunctionalization of alkenes, explored for over 100 years, offers the potential for a direct, atom-economical approach to value-added products. While thermodynamically favored, the kinetic barrier to such processes necessitates the use of catalysts to control selectivity and reactivity. Modern variants typically rely on noble metals that require different ligands for each class of hydrofunctionalization
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.
The TMSI-catalyzed reaction of aldehydes and ketones with alkoxydimethylsilanes gave unsymmetrical ethers in good to high yields. This reductive etherification is superior to the conventional method using two kinds of silicon reagents in terms of atom efficiency and ease of operation.
