Bismuth Trichloride as a New Efficient Catalyst in the Aldol Reaction and the Michael Reaction

Article abstract of DOI:10.1246/bcsj.64.990

In the presence of a catalytic amount of bismuth(III) trichloride (5 mol percent), silyl enol ethers react with aldehydes at room temperature in dichloromethane to give the corresponding aldols in good yields.Silyl enol ethers also have been found to reac
