Planar polycyclic aromatic hydrocarbons have important applications in optoelectronics,environmental chemistry and cancer researches.An improved sono-chemical synthetic procedure of dibenz[a,c]anthracene(D[a,c]A)was reported in this work.The yield was increased to 56％ and the resultant was carefully characterized via gas chromatography-electron impact mass spectrometry(GC-EIMS),matrix assisted laser desorption ionization-time of flight (MALDI-TOF),1H NMR,13C NMR,correlation spectrometry(1H-1H COSY),heteronucl.ear multiple bond correlation(HMBC)and heteronuclear multiple quantum coherence(HMQC).Based on the characterization data,we proposed a 4-step mechanistic explanation for the formation of D[a,c]A under sono-chemical bis-ortho-Wittig reaction conditions.
