Solvent decides: Versatile coppernanoparticles (Cu NPs) on activated carbon have been found to catalyze the multicomponent synthesis of indolizines in dichloromethane and the synthesis of heterocyclicchalcones in the absence of solvent, in both cases, from pyridine‐2‐carbaldehyde derivatives, secondary amines, and terminal alkynes (see scheme).
