Abstract
This paper reports that the reaction of the propargyl bromides with al dehydes promoted by powdered lead in aqueous media. The selectivity an d possible mechanism of these reactions are discussed. The yields of p roducts for reaction of propargyl bromide are 31 similar to 71%. The r atios of allenyl alcohol and homopropargyl alcohol are 1:1.5 to 1:3. T he product for reaction of phenyl propargyl bromide is allenyl alcohol and the yields are 52 similar to 84%.
