Conjugated quinolines were synthesized by the reaction between aminobenzophenones and various diacetyl compounds such as diacetyl phenothiazine, diacetylcarbazole, and diacetyl biphenyl and di/triacetyl benzene under solvent‐free microwave irradiation in 12–98% yields. Symmetrically substituted oligoquinolines were predominantly formed within 12 min in the presence of 0.5 equiv of diphenylphosphate catalyst without any solvent.
