One-pot reactions of gallium powder, trimethylsilylpropargyl bromide, aldehydes or ketones in the presence of KI and LiCl show very high acetylenic selectivity and under the same conditions, trimethylsilylallyl bromide also exhibits very high selectivity favoring α-adducts.
镓粉,三甲基甲硅烷基炔丙基溴,醛或酮在KI和LiCl存在下的一锅反应显示出很高的炔属选择性,在相同条件下,三甲基甲硅烷基烯丙基溴也表现出非常高的选择性,有利于α加合物。
