摘　　要：The chemodivergent ring-opening of cyclobutanols is described under the carbocatalytic assistance of graphene oxide(GO).The protocol enables the synthesis of diversely functionalized dienes or indenes(26 examples)based on the amount of GO employed.Spectroscopic(XPS and ssNMR)as well as experimental investigations revealed a direct involvement of theπ-domains of GO in tuning the stability of carbocationic intermediates during the reaction.
