Reduced graphene oxide supported piperazine in aminocatalysis

摘要

Reduced graphene oxide (rGO) has been used as a support for piperazine to provide a heterogeneous bifunctional organocatalyst (rGO-NH) that is able to efficiently promote vintage organic transformations such as Knoevenagel Michael and aldol reactions. The obtained results suggest a significant role of the support in the course of these reactions.
