摘要

The first transition metal-free highly stereoselective positional isomerization of various a-alkyl styrenes through a carbocation mech-anism triggered strategy is developed by using AI(OTf)3 as a hidden Br?nsted acid catalyst,which provides facile access to value-added acyclic tri-and tetra-substituted alkenes in good yields with high stereoselectivity under mild conditions.
