Oxy‐gone in a tandem: A catalytic system composed of metal nanoparticles (NPs) and a functionalized Brønstedacidicionicliquid (IL), both of which are immobilized in a nonfunctionalized IL, is highly efficient in upgrading lignin‐derived phenolic compounds into alkanes; the hydrogenation and dehydration reactions take place in tandem.

was effectively prepared by a multicomponentreaction, employing aminomethanesulfonic acid, glyoxal, and formaldehyde. The catalytic activity of bsmim was tested in the synthesis of quinolinederivatives, by means of the Friedländer reaction, and in the allylic substitution of alcohols with nitrogen-containing heterocycles. The performance of sulfo-imidazole derivative (bsmim) resulted in higher comparison
