{ALF} Rearrangement by BF3 etherate leads directly to the ethyl ester: Rec. Trav. Chim., 78, 664 (1959); Chem. Lett., 1129 (1981); 241, 1271 (1982). See also Chloroacetaldehyde diethyl acetal, L07661.

{ALF} The Grignard reagent, prepared by exchange with ethyl magnesium bromide, adds to carbonyl compounds to give carbinols which rearrange in acid to ɑß-unsaturated acids. Alternatively, partial reduction of the adduct followed by hydrolysis provides a route to ɑß-unsaturated aldehydes: J. Chem. Soc., 1823 (1949); Rec. Trav. Chim., 82, 305 (1963):

{ALF} Adds to carbonyl compounds in the presence of ZnBr2: Can. J. Chem., 54, 2310 (1976).
