水溶液中金属铅诱发芳香醛的烯丙基化反应
Allylation Reactions of Aromatic Aldehydes with Plumbum in Aqueous Media
【摘要】 超声辐射下,在Pb-THF-NH4Cl-H2O体系中,烯丙基溴与一系列芳香醛室温反应4h,得62%～98%烯丙基化产物;而同样体系中搅拌20h,高烯丙基醇产率为63%～97%。
【Abstract】 The allylation reactions of aldehydes with allyl bromide were carried out in 62%～98% yield with Pb-THF-NH4Cl-H2O under ultrasound irradiation at room temperature for 4h.The reactions in the same system gave homoallylic alcohols in 63%～97% yield under stirring for 20h.
