Sulfonic acid functionalized metal-organic framework (S-IRMOF-3): A novel catalyst for sustainable approach towards the synthesis of acrylonitriles

Rather, Ryhan Abdullah,Siddiqui, Zeba N.

, p. 15749 - 15762 (2019/06/10)

A sulfonic acid functionalized metal-organic framework (S-IRMOF-3) has been synthesized by dropwise addition of chlorosulfonic acid (0.5 mL) in IRMOF-3 (1 g) containing 20 mL of CHCl3 at 0 °C under simple stirring. The catalyst was applied in K
