| 1 | Lead-promoted Barbier-type reaction of aldehydes with propargyl bromides in aqueous media显示文摘This paper reports that the reaction of the propargyl bromides with aldehydes promoted by powdered lead in aqueous media.The selectivity and possible mechanism of these reactions are discussed.The yields of products for reaction of propargyl bromide are 31~71%.The ratios of al-lenyl alcohol and homopropargyl alcohol are 1:1.5 to 1:3.The product for reaction of phenyl propargyl bromide is allenyl alcohol and the yields are 52~84%. | Zhou, JY Sun, GF Zhang, MF Jia, Y Wu, SH | 1997 | Chinese Journal of Chemistry1997，15，4： | 2 |
