Ir‐β Zeolite as a Heterogeneous Catalyst for the One‐Pot Transformation of Citronellal to Menthol.

Homogeneous and heterogeneous catalysts for multicomponent reactions

“…When metal nanoparticles are formed on the internal and/or external surface of acid zeolites, bifunctional hydrogenation/dehydrogenation-acid solid catalysts are obtained [40][41][42][43] allowing zeolites to catalyze multistep multistep reactions. [44][45] There are reactions that require sites with acid strength stronger than that of zeolites. Then, solid catalysts containing sulfonic groups can be used.…”
