摘要 The evidence for the sp2 C-H …O=C intramolecular interaction like hydrogen bond observed from the 1H NMR signal shifted extremely to down field (δ= 10.23 ppm ) at the bay area of phenaleno[2,3-f] quinolin-13-one has been confirmed by EIMS and MS / MS(CAD ) spectroscopy and IR spectroscopy, as well as MNDO-PM3 calculations.
