A robust catalytic system mediates metal‐free and solvent‐free C–C and C–N bond formation by favoring the interaction between the reactants due to the presence of carboxylicacid moieties and chloride counterion, providing a sustainable protocol with appropriate environmental impact.

Polysubstitutedquinolines were efficiently prepared on the soluble polyethylene glycol (PEG) by microwave irradiation Friedländer condensation of PEG boundacetoacetate with 2‐aminoarylketones promoted by catalytic amount of polyphosphoric acid, and subsequently cleavage from the PEG with MeONa in MeOH. The polymer‐supported synthesis provided the target compounds in excellent yield and purity with
