▎ 摘　　要

Graphene oxide (GO) and carboxylic acid functionalized GO (GO-CO2H) have been found to efficiently promote the heterogeneous and environmentally friendly pinacol rearrangement of 1,2-diols and the direct nucleophilic substitution of allylic alcohols. In general, high yields and regioselectivities are obtained in both reactions using 20 wt% of catalyst loading and mild reaction conditions.
