The reaction of but-2-enyltributylstannane with certain aldehydes in the presence of AlCl3–PriOH produces the α-adduct (3) either predominantly or exclusively, while the reaction in the presence of ordinary Lewis acids, such as TiCl4, SnCl4, and BF3·OEt2, affords the γ-adduct (2) exclusively.
但-2- enyltributylstannane与在的AlCl存在某些醛反应3 -Pr我OH产生α-加合物(3)任一主要或排他地,而在普通的路易斯酸,如的TiCl存在下进行反应4, SnCl 4和BF 3 ·OEt 2仅提供γ-加合物(2)。
