Graphene or grapheneoxide (GO) has many advantages, such as large specific surface area,
excellent thermal conductivity, high electrical mobility and great mechanical strength, which
has been widely used in synthesizing nanocomposites and fabricating microelectrical
devices[1,2]. Ionic liquid/graphene oxide composite was prepared by treating commercially
available expandable graphite powder using a modified Hummers method. The structure of
catalyst was characterized by various techniques such as Fourier transform infrared
spectroscopy (FTIR), and TG-DTA, and the spectral data confirmed were the structures of the
title catalyst [3]. As part of our continuing efforts to develop green and sustainable chemistry
for useful organic transformations, herein we have used ionic liquid/graphene oxide as a
convenient, clean and highly efficient catalyst for ring opening of epoxides at room
temperature. The most important features of this procedure are an environmentally benign
catalyst and solvent, effective recovering and reusability of the catalyst, operational
simplicity and short reaction times (Figure 1).
