Abstract: Bismuth metal, upon activation by zinc fluoride, can effect the crossed aldol reaction between α-bromocarbonyl compounds and aldehydes in aqueous media. The reaction was found to be regiospecific and syn-diastereoselective.Key words: bismuth, zinc fluoride, aldol reaction, regioselectivity, aqueous media.
