摘　　要：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）,1 H NMR,13 C NMR,correlation spectrometry（1 H1 H COSY）,heteronuclear 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.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）,1 H NMR,13 C NMR,correlation spectrometry（1 H1 H COSY）,heteronuclear 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.
