Mild Lewis acid, often used as its diethyl ether complex; for a brief review of this reagent, see: Synlett, 649 (2002). The complex promotes formation of dithioacetals from aldehydes and dithiols: J. Org. Chem., 59, 4665 (1994), Michael additions of silyl enol ethers: J. Org. Chem., 60, 5024 (1995), and rearrangement of epoxides to carbonyl compounds, giving better selectivity than BF3: J. Org. Chem., 61, 1877 (1996). Efficient catalyst for transesterification of ß-keto esters under near-neutral conditions: Synlett, 1338 (2001)./n
