Activity, recovery and task-specific action should be considered, for designing of any novel catalyst. Homogenous catalysts have high activity but their recovery and separation from reaction mixture is difficult so that heterogeneous catalysts can be easily separated and reused but their activity is low [1]. Utilizing the nano catalysts can improve the efficiency of heterogeneous catalysis due to their high surface to volume ratio [2]. Increasing the catalyst s surface will increase the contact between catalyst and reactant. Thus improvement of the activity of the catalyst will be occurred [3]. In continuation of our studies on the knowledge-based development of nano catalysts and ring opening of epoxides, herein we wish to report 1-methyl-1Himidazol- 3-ium 2,3,4,5,6-pentafluorophenolate [mim]C6F5O as a novel hydrophilic and reusable nano catalyst for synthesis of β-azido alcohols from the corresponding epoxides in water at 80 °C
