Abstract: [Figure not available: see fulltext.]Indenoquinolinones have been synthesized from 2-haloquinoline-3-carbaldehyde through Pd-mediated simultaneous C–H (aldehyde) and C–X bond activation. DFT studies were performed to investigate the mechanistic pathway, and in situ UV–Vis studies indicate the presence of Pd(II) intermediate species. Aryne ligated Pd complex is actual intermediate in these reactions. Ligation of reactive aryne to Pd reduces probability of side reactions. Graphic abstract: [Figure not available: see fulltext.]
