propargyl bromides having substituents at the γ-position and gallium in the presence of 5 mol % of indium with aldehydes and ketones selectively produced homoallenyl alcohols in good to excellent yields. Treatment of organogallium reagents obtained from propargyl bromide or propargyl bromides having substituents at the α-position and gallium in the presence of 5 mol % of indium with carbonyl compounds selectively
在5mol%的铟存在下,由在γ-位具有取代基的炔丙基溴和镓产生的有机镓试剂与醛和酮的反应选择性地以良好或优异的产率产生了高均烯基醇。在5mol%的铟存在下,用羰基化合物处理由在α位具有取代基的炔丙基溴或炔丙基溴和镓获得的有机镓试剂,选择性地得到高炔丙醇。
