[reaction: see text] Ytterbium trifluoromethanesulfonate [Yb(OTf)3] catalyzed the imino ene reaction of N-tosyl aldimine with alpha-methylstyrene to give a homoallylamine in moderate yield. Furthermore, addition of a catalytic amount of chlorotrimethylsilane (TMSCI) dramatically enhanced the imino ene reaction.
[反应：见正文] 三氟甲磺酸镱 [Yb(OTf)₃] 催化 N-对甲苯磺酰基醛亚胺与α-甲基苯乙烯的亚氨基烯反应，以中等产率得到高烯丙基胺。此外，加入催化量的三甲基氯硅烷（TMSCI）显著增强了亚氨基烯反应。
