Reduced graphene oxide supported piperazine in aminocatalysis

Reduced graphene oxide (rGO) has been used as a support for piperazine to provide heterogeneous bifunctional organocatalyst (rGO-NH) that is able to efficiently promotvintage organic transformations such as Knoevenagel, Michael and aldol reactions. The obtained results suggest a significant role of the support in the course of these reactionsWe thank the Spanish Government (CTQ-2012-35957) and CAM (AVANCAT CS2009/PPQ-1634) for financial support. E.R. thanks the Spanish Ministry for a predoctoral fellowship (FPU/AP-2010-0807). R.S. thanks the Spanish Ministry of Science for a postdoctoral contract (PTQ-11-04601
